kernel: dm log: fix out-of-bounds write due to region_count overflow

A flaw was found in the Linux kernel's device-mapper log dm log component. A local attacker could exploit an integer overflow vulnerability where a 64-bit value is truncated to 32 bits, leading to undersized memory allocations. This allows for out-of-bounds writes to kernel memory during log...

DEBIAN-CVE-2026-70652

libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, libvips built with libultrahdr support can incorrectly size an output buffer in libvips/foreign/uhdrsave.c within vipsforeignsaveuhdrsetrawhdr when a pipeline enlarges an incoming JPEG to a very large outpu...

CVE-2026-64548

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...

postgresql: integer overflow can cause an undersized allocation and an out-of-bounds write

A flaw was found in PostgreSQL. An integer overflow in multiple server features allows an unprivileged database user to cause an undersized memory allocation that leads to an out-of-bounds write. This issue allows an attacker to execute arbitrary code as the operating system user running the...
