| In the Linux kernel, the following vulnerability has been resolved:
netfs: Fix writeback error handling
Fix the error handling in writeback_iter() loop. If an error occurs,
writeback_iter() needs to be called again with *error set to the error so
that it can clean up iteration state. Further, the current folio needs
unlocking and redirtying. |
| In the Linux kernel, the following vulnerability has been resolved:
net: phy: sfp: free mii_bus in sfp_i2c_mdiobus_destroy
sfp_i2c_mdiobus_create() allocates the I2C MDIO bus with mdio_i2c_alloc(),
a plain (non-devm) allocation, and registers it. sfp_i2c_mdiobus_destroy()
only unregisters the bus and clears sfp->i2c_mii without calling
mdiobus_free(). As the only reference to the bus is then cleared, the
struct mii_bus is leaked.
This is hit whenever a copper/RollBall SFP module that instantiated an MDIO
bus is removed: sfp_sm_main() takes the global teardown path and calls
sfp_i2c_mdiobus_destroy(). sfp_cleanup(), on driver unbind, frees
sfp->i2c_mii directly, which is why the leak only triggered on module
hot-removal and not on unbind.
Free the bus in sfp_i2c_mdiobus_destroy() to match the allocation done in
sfp_i2c_mdiobus_create(). |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix insn_aux_data leak on verifier err_free_env path
When bpf_check() allocates env->insn_aux_data successfully but later
fails to allocate env->succ, it jumps directly to err_free_env.
The existing vfree(env->insn_aux_data) sits before the err_free_env
label, so that direct jump bypasses it and leaks insn_aux_data.
Move vfree(env->insn_aux_data) into err_free_env so all early and late
exit paths release it consistently. |
| In the Linux kernel, the following vulnerability has been resolved:
octeontx2-pf: Fix leak of SQ timestamp buffer on teardown
The send-queue timestamp ring is allocated with qmem_alloc() when
timestamping is used, but otx2_free_sq_res() never freed sq->timestamps,
leaking that memory across ifdown and device removal. Add the missing
qmem_free() alongside the other SQ companion buffers. |
| In the Linux kernel, the following vulnerability has been resolved:
apparmor: aa_label_alloc use aa_label_free on alloc failure
aa_label_alloc() allocates a secid before allocating or taking the label
proxy. If the later proxy step fails, the error path only freed the label
memory, leaking any resources initialized by aa_label_init().
Use aa_label_free() on the failure path so partially initialized labels
release their secid and other label resources before the backing memory is
freed. |
| In the Linux kernel, the following vulnerability has been resolved:
xprtrdma: Sanitize the reply credit grant after parsing
The out_norqst exit in rpcrdma_reply_handler() branches away before
the credit clamp, so a reply that matches no pending request reaches
out_post carrying the raw credit value parsed from the wire.
rpcrdma_post_recvs() does not bound its @needed argument: the refill
loop allocates and chains Receive WRs until the count is satisfied or
allocation fails. A peer that sends a well-formed reply carrying an
unknown XID and an inflated credit grant therefore drives rep
allocation and Receive posting past re_max_requests on every such
reply.
Move the clamp to immediately after the credit field is parsed,
ahead of the first branch that can reach out_post, so every later
consumer sees a sanitized value. The cwnd update stays on the
matched-request path. |
| In the Linux kernel, the following vulnerability has been resolved:
riscv: mm: Fix out-of-bounds page-table walk during memory hot-remove
remove_pud_mapping() and remove_p4d_mapping() obtain a child table base
with pud_offset(p4dp, 0) and p4d_offset(pgd, 0), then add the index for
addr.
RISC-V folds page-table levels at runtime. When a level is folded, its
offset helper returns the parent entry itself, but the index can still be
nonzero. Adding it walks past the parent table. Sv48 folds P4D, while Sv39
folds both P4D and PUD, so memory hot-remove can descend into unrelated
memory and pass an invalid page to __free_pages(). This can trigger:
kernel BUG at include/linux/mm.h:1810!
VM_BUG_ON_PAGE(page_ref_count(page) == 0)
arch_remove_memory+0x1e/0x5c
try_remove_memory+0x15e/0x200
remove_memory+0x24/0x3c
Only add the index when the corresponding page-table level is enabled,
matching p4d_offset() and pud_offset(). |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/core: Fix FRMR aging push to queue error flow
Aging pools with pinned handles requires moving handles from the
active queue to a non-empty inactive queue that might fail on new page
allocation, we are currently not handling the fault and leaking any mkey
that fails the push.
Fix by Introducing push_queue_to_queue_locked() that fills the
destination's partial tail page from the source and then splices the
remaining source pages onto the destination, performing no allocation.
Replace the per-handle move loop in age_pinned_pool() and the
open-coded splice in pool_aging_work() with calls to the helper.
As the helper cannot fail under memory pressure, removing a class of
GFP_ATOMIC allocations under the pool lock and simplifying the error
flow. |
| In the Linux kernel, the following vulnerability has been resolved:
vfio/qat: fix f_pos race in qat_vf_resume_write()
qat_vf_resume_write() checks filp->f_pos before taking migf->lock, but
copies into the migration-state buffer after taking the lock and
re-reading the shared file position.
Two concurrent writers could therefore pass the bounds check with the
old offset, then have the second writer copy after the first advanced
f_pos, writing past the end of the migration-state buffer.
Take migf->lock before doing the boundary checks. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7921: fix resource leak in probe error path
When pcim_iomap_region() or devm_kmemdup() fail, the code returns
directly without cleaning up previously allocated resources:
- mt76_device allocated by mt76_alloc_device()
- pci irq vectors allocated by pci_alloc_irq_vectors()
Fix this by jumping to the existing error cleanup path instead of
returning directly. |
| In the Linux kernel, the following vulnerability has been resolved:
iommufd: Destroy the pages content after detaching from dmabuf
Sashiko points out this has gotten out of order, the mutex could still be
in use through the dmabuf invalidation callbacks. Don't destroy any of the
pages content until the dmabuf is fully detached. |
| In the Linux kernel, the following vulnerability has been resolved:
nvme-pci: fix out-of-bounds access in nvme_setup_descriptor_pools
nvme_setup_descriptor_pools() indexes dev->descriptor_pools[] using the
numa_node forwarded from hctx->numa_node by its single caller,
nvme_init_hctx_common(). On a non-NUMA kernel hctx->numa_node is
NUMA_NO_NODE (-1). Because the parameter was declared 'unsigned', the
value becomes UINT_MAX and the index walks off the array (sized to
nr_node_ids), faulting during nvme_alloc_ns() and leaving the namespace
without a /dev node.
Reproduces on any NVMe controller probed by a CONFIG_NUMA=n kernel:
BUG: unable to handle page fault for address: ffff889101603d38
RIP: 0010:nvme_init_hctx_common+0x5a/0x190 [nvme]
Call Trace:
nvme_init_hctx+0x10/0x20 [nvme]

nvme_scan_ns_async+0x23/0x30 [nvme_core]
Switch the parameter to int and fall back to node 0 when it is
NUMA_NO_NODE; node 0 is always present. |

drm/syncobj: Fix memory leak in drm_syncobj_find_fence()
Commit 18226ba52159 ("drm/syncobj: reject invalid flags in
drm_syncobj_find_fence") forgot to take into account the fact that
drm_syncobj_find() takes a reference to syncobj and returns early
without dropping the reference, leading to memory leaks.

| In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Fix leak when pinning ubuf pages
When pin_user_pages_fast() returns fewer pages than requested, the pages
that were successfully pinned are not released, leading to a leak.
Fix this by unpinning any partially pinned pages before returning failure. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/vc4: Supply the overflow slot size in BPOS, not the whole bin BO size
vc4_overflow_mem_work() points BPOA at a 512KB slot inside the 16MB
binner BO, but writes the size of the whole BO to BPOS. On every binner
out-of-memory event the PTB is therefore authorized to write tile lists
across all the other slots (which may hold the tile state, tile alloc and
overflow memory of in-flight jobs) and, for any slot but the first, past
the end of the binner BO into unrelated CMA memory.
Since CMA pages are recycled into page cache and user allocations, this
is arbitrary memory corruption by GPU DMA. In practice it shows up as GPU
hangs with corrupted control list pointers, userspace heap corruption, a
GPU that stays permanently wedged after the first hang, and occasional
full system crashes, whenever a job overflows the initial binner slot.
The bug dates back to the conversion from a dedicated overflow BO (where
writing the full BO size was correct) to the slotted binner BO. |
| An issue exists in pson EH-TW5350 Epson iProjection.apk v3.2.6. If you identify a projector equipped with an iProjection function, you can access the projector using hard-coded authentication information and control the projector maliciously. |
| In the Linux kernel, the following vulnerability has been resolved:
can: etas_es58x: es58x_read_bulk_callback(): fix RX buffer leak on URB resubmit failure
es58x_read_bulk_callback() resubmits the RX URB after processing a received
packet. If the resubmit succeeds, the URB remains anchored and will be
handled by the normal RX path or by teardown.
However, if usb_submit_urb() fails, the callback unanchors the URB and then
returns directly. This skips the existing free_urb path, so the coherent
transfer buffer allocated with usb_alloc_coherent() is not released.
Reuse the existing free_urb path after a resubmit failure so that the RX
coherent buffer is freed before leaving the callback. |
| In the Linux kernel, the following vulnerability has been resolved:
net: sxgbe: free TX rings on RX allocation failure
When RX descriptor ring allocation fails, init_dma_desc_rings() only
frees the partially allocated RX rings and returns. The TX rings that
were allocated earlier in the same function are leaked.
Rearrange error labels to clean up TX rings upon RX failures. |
