CVSS v3.1 |
| libheif is a HEIF and AVIF file format decoder and encoder. From 1.22.0 until 1.23.2, a crafted HEIF, HEIC, or AVIF item graph using nested iden and auxl references can make HeifPixelImage::transfer_channel_from_image_as() append duplicate Alpha planes with different bit depths to m_storage. HeifPixelImage::scale_nearest_neighbor() in libheif/image/pixelimage.cc allocates the destination Alpha plane using the first plane's 8-bit depth, then iterates a later 10-bit or 12-bit Alpha component and writes uint16_t samples into the same 8-bit allocation. The output geometry controls the overflow extent and the encoded sample values control the data written, allowing a remote file processed by heif_decode_image() to cause a heap out-of-bounds write. This issue is fixed in version 1.23.2. |
| In Vinyl Cache before 9.0,2, workspace buffer overflow vulnerability was found in the .upper() and .lower() string type methods of VCL. This can be used as a remote denial of service (DoS) vector to make the child process segfault or assert, and then restart. Effectively exploiting this vulnerability requires prior knowledge about the VCL in use and the ability to craft a request that contains a string that is long enough to fill the remaining workspace at the call site while staying under the different request size limits (http_req_size, http_req_hdr_len, etc.). |
| An out-of-bounds write vulnerability exists in some of the Ethernet switches because of improper validation of the username field length during Web login processing. This may allow a remote attacker to submit a specially crafted overly long input, triggering a buffer overflow that can cause the authentication process to crash and result in a Denial of Service (DoS) attack. |
| In the Linux kernel, the following vulnerability has been resolved:
cpufreq: imx6q: fix out-of-bounds write when probed more than once
imx6_soc_volt is allocated fresh on every probe, sized to the number of
ARM OPPs:
imx6_soc_volt = devm_kcalloc(cpu_dev, num, sizeof(*imx6_soc_volt),
GFP_KERNEL);
but it is filled through soc_opp_count, which has static storage and is
never reset. A second bind after an unbind keeps indexing from where the
first one stopped, and writes past the end of the new array.
Unbinding and rebinding the driver on qemu's mcimx6ul-evk, under KASAN:
BUG: KASAN: slab-out-of-bounds in imx6q_cpufreq_probe+0x3b0/0xa34
Write of size 4 at addr c5e90480 by task binder/73
imx6q_cpufreq_probe from platform_probe+0x88/0xe4
platform_probe from really_probe+0x108/0x384
bind_store from kernfs_fop_write_iter+0x1b4/0x28c
The write lands one u32 past the end of the allocation.
soc_opp_count is only read a few lines below the loop that fills it, so it
never needed static storage. Make it a local. |
| In the Linux kernel, the following vulnerability has been resolved:
nfc: llcp: avoid userspace overflow on invalid optlen
nfc_llcp_getsockopt() casts optval to (u32 __user *) for put_user(), so
the kernel always stores 4 bytes regardless of the caller-supplied
optlen. The existing min_t(u32, len, sizeof(u32)) only clamps the length
reported back to userspace; it does not constrain the store. A call with
optlen < 4 therefore writes past the user buffer, violating the
getsockopt(2) contract for all five supported optnames.
Reject any call with optlen < sizeof(u32) up front. 'len' is int, so a
plain size comparison would promote a negative optlen to size_t and slip
past the check; an explicit 'len < 0' test is added first to catch
negative values before the size compare. |

| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7996: fix out-of-bounds link array access in mt7996_tx()
When mac80211 leaves the link unspecified, mt7996_tx() substitutes the
primary link id of the station or vif. That value is
IEEE80211_LINK_UNSPECIFIED (0xf) until the first link has been added,
and it is then used unchecked to index vif->link_conf[],
mvif->mt76.link[] and sta->link[], all of which hold
IEEE80211_MLD_MAX_NUM_LINKS (15) entries.
Clamp the primary link id to the default link before using it, and use
the clamped value for the link_sta fallback as well. |

| In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: fix out-of-bounds access in mmio copy helpers
mt76_mmio_write_copy() and mt76_mmio_read_copy() iterate up to
ALIGN(len, 4), so a length that is not a multiple of four reads past the
source buffer (write_copy) or writes past the destination (read_copy).
Copy the aligned body in the loop and handle the remaining tail through a
4-byte bounce buffer, keeping the register access width unchanged. |
| In the Linux kernel, the following vulnerability has been resolved:
nvme-fc: unmap cmd_iu DMA on rsp_iu mapping failure in init_request
__nvme_fc_init_request() maps cmd_iu and then rsp_iu for DMA. If the
rsp_iu mapping fails, the original code only recorded the error and fell
through: it left the already-mapped cmd_iu unmapped and still marked the
op as FCPOP_STATE_IDLE before returning. Since blk-mq does not call
.exit_request() when .init_request() fails, the cmd_iu mapping is leaked
for every op whose rsp_iu mapping fails.
Jump to an error path on rsp_iu mapping failure that unmaps cmd_iu and
returns the error without marking the op idle, so it stays in the
FCPOP_STATE_UNINIT state set by the initial memset(). |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix offset warn check for bpf_res_spin_lock
Sashiko pointed out correctly that the case statement for
BPF_RES_SPIN_LOCK incorrectly checks offset for BPF_SPIN_LOCK.
Fix it by checking res_spin_lock_off instead. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: fix counter type in iwl_fwrt_dump_error_logs
The loop counter 'count' was declared as u8 while num_pc is u32.
If firmware advertises more than 255 PC entries the counter wraps
back to zero and the loop never terminates potentially causing an
infinite loop or reading past the allocated pc_data array.
Change the declaration to u32 to match num_pc. |
| In the Linux kernel, the following vulnerability has been resolved:
media: rtl2832_sdr: use vb2_video_unregister_device() on remove to fix DMA leak
rtl2832_sdr_remove() runs on USB disconnect and clears dev->udev to
NULL before any pending streaming teardown has run. When user space
later closes its file descriptor, vb2 calls rtl2832_sdr_stop_streaming()
which in turn calls rtl2832_sdr_free_stream_bufs(). That helper releases
each coherent buffer with:
usb_free_coherent(dev->udev, dev->buf_size,
dev->buf_list[dev->buf_num],
dev->dma_addr[dev->buf_num]);
usb_free_coherent() returns immediately when its dev argument is NULL,
so every DMA stream buffer that was live at disconnect is silently
leaked. The URBs allocated in rtl2832_sdr_alloc_urbs() outlive the
device for the same reason.
The rtl2832_sdr driver uses vb2_fop_release() in its file_operations,
so replace video_unregister_device(&dev->vdev) with
vb2_video_unregister_device(&dev->vdev) and move it before clearing
dev->udev. vb2_video_unregister_device() releases the vb2 queue, which
synchronously runs rtl2832_sdr_stop_streaming() if streaming is active,
so URBs and coherent DMA stream buffers are freed while dev->udev is
still valid.
vb2_video_unregister_device() locks vdev->queue->lock (vb_queue_lock)
internally, and stop_streaming() locks v4l2_lock, so the previous outer
mutex_lock(&dev->vb_queue_lock) / mutex_lock(&dev->v4l2_lock) pair
around the unregister sequence would self-deadlock and has been removed.
A short v4l2_lock critical section around dev->udev = NULL remains so
any ioctl path that still holds the file descriptor sees coherent state.

| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: debug: fix off by on in rtw89_ppdu_str()
This > comparison should be >= to avoid an out of bounds access. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/bnxt_re: Clear VM_MAYWRITE on DBR/toggle page mmap
bnxt_re_mmap() rejects VM_WRITE for the DBR_PAGE and TOGGLE_PAGE mmap
flags, but a read-only mapping can still retain VM_MAYWRITE. nd later
be upgraded with mprotect(PROT_WRITE). This can bypass the write check
that only runs at mmap time.
Clear VM_MAYWRITE before vm_insert_page() in the shared DBR/toggle-page
branch, matching the existing policy that userspace writes are not
expected for these pages. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: core: Validate connected lane counts
The connected lane count is used by TX equalization code to index arrays
sized by UFS_MAX_LANES. Reject zero and out-of-range RX or TX lane counts
before they can be propagated. |
