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...

Astra Linux – Vulnerability in Linux 6.12

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-2026-64548

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...
