kernel: accel/qaic: Add overflow check to remap_pfn_range during mmap

A flaw was found in the Linux kernel's accel/qaic driver. This vulnerability allows for memory to be mapped beyond its intended boundaries during certain memory allocation operations. A local attacker could exploit this flaw, leading to a use-after-free condition. This could potentially result in...

AZL-99452 CVE-2026-80814 affecting package kernel 6.6.150.1-1

In the Linux kernel, the following vulnerability has been resolved: rndishost: add overflow check in rndisrxfixup Add an overflow check to ensure that dataoffset + datalen + 8 does not wrap, which would enable an OOB read of the USB data buffer...

CVE-2026-80814

A vulnerability in the Linux kernel 's rndis_host driver (a USB RNDIS host driver) was identified in the rndis_rx_fixup() function. The root cause is a missing overflow check: if data_offset + data_len + 8 wraps around, it enables an out-of-bounds (OOB) read of the USB data buffer. The fix, as de...

Linux Distros Unpatched Vulnerability : CVE-2026-80814

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - rndishost: add overflow check in rndisrxfixup Add an overflow check to ensure that dataoffset + datalen + 8 does not wrap, which would enable an OOB read of the...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: fs/ntfs3: Enhanced the attribute size check This combines the overflow and boundary check so that all attribute sizes will be properly examined during enumeration. 169.181521 BUG: KASAN: Out-of-bounds access in...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: xsk: Added a missing overflow check in xdpumemreg. The number of chunks can exceed the range of u32. Ensure that -EINVAL is returned in case of an overflow. Also, removed a redundant u32 cast when assigning umem-npgs...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: fs/ntfs3: Added a overflow check for attribute size. The offset addition could cause an overflow, potentially passing the used size check when processing attributes with very large sizes e.g., 0xffffff7f. This could lead to...

EUVD-2026-59635

In the Linux kernel, the following vulnerability has been resolved: ntfs: harden runlist realloc size calculations Add a shared helper to safely convert runlist element counts to byte sizes using overflow checks, and use it in both ntfsrlrealloc and ntfsrlreallocnofail...

CVE-2026-68253

In the Linux kernel, the following vulnerability has been resolved: drm/i915/hdcp: check streams bounds before overflow The data-streams overflow check is done after the buffer overflow has already happened. Move the overflow check before the write. Side note, emitting a warning splat with a...

CVE-2026-68253

CVE-2026-68253 affects the Linux kernel’s drm/i915/hdcp component. The issue arises because the check for streams[] bounds is performed after a potential buffer overflow has already occurred during a write, allowing memory corruption. The fix moves the overflow bound check before the write, preve...

CVE-2026-11743 Missing negative-offset/overflow check in SF32LB MPI QSPI NOR flash driver allows out-of-bounds read and write

The SF32LB MPI QSPI NOR flash driver drivers/flash/flashsf32lbmpiqspinor.c validated the flash offset and length on its read and write paths with the test offset + size data-size. Because offset is a signed offt while size is unsigned, a negative offset is converted to a large unsigned value and...

CVE-2026-11743

The CVE concerns the SF32LB MPI QSPI NOR flash driver (drivers/flash/flash_sf32lb_mpi_qspi_nor.c). The vulnerability arises in the read/write paths where a signed offset (off_t) is compared against an unsigned size using (offset + size) > data->size, allowing a negative offset to wrap to a ...

CVE-2026-64544

In the Linux kernel, the following vulnerability has been resolved: crypto: asymmetrickeys - fix OOB read in pefiledigestpecontents pefiledigestpecontents computes the trailing-data hash length as pelen - hashedbytes + certssize. A crafted PE can make the addition exceed pelen, causing the unsign...

CVE-2026-64548

The CVE-2026-64548 vulnerability affects the Linux kernel’s BPF/sockmap path. A truncation can occur in bpf_msg_push_data when the scatterlist ring is full or nearly full: len (from BPF ARG_ANYTHING) and copy size are both u32, and the code path uses copy + len to compute a page allocation. An at...

CVE-2026-64548 bpf, sockmap: reject overflowing copy + len in bpf_msg_push_data()

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: reject overflowing copy + len in bpfmsgpushdata When the scatterlist ring is full or nearly full, bpfmsgpushdata enters a copy fallback path and computes copy + len for the page allocation size. Since len comes from...
