SUSE CVE-2026-53178

In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: rtwmlme: add bounds checks before ielength subtraction Add guards to ensure ielength is large enough before subtracting fixed IE offsets to prevent unsigned integer underflow...

CVE-2026-53178

A flaw was found in the Linux kernel, specifically within the rtl8723bs Wi-Fi driver's rtwmlme component. This vulnerability is due to a missing bounds check before subtracting fixed offsets from the ielength variable, which can lead to an unsigned integer underflow. This issue could potentially...

Astra Linux – Vulnerability in gpsd

There is an integer underflow vulnerability in the nextstate function in gpsd/packet.c in gpsd versions prior to the commit ffa1d6f40bca0b035fc7f5e563160ebb67199da7. When parsing a NAVCOM packet, the payload length is calculated using lexer-length = sizetc - 4, without checking whether the input...

Astra Linux – Vulnerability in libheif

libheif is a decoder and encoder for HEIF and AVIF file formats. In versions 1.21.2 and earlier, a crafted 792-byte HEIF sequence file with samplesperchunk=0 in the stsc field could cause an unsigned integer underflow in the Chunk constructor mlastsample = 0 + 0 - 1 = UINT32MAX, causing all sampl...

CVE-2026-47222 NanaZip: Heap out-of-bounds read in NanaZip AVB property descriptor parser via unsigned integer underflow

NanaZip is the 7-Zip derivative intended for the modern Windows experience. From version 3.0.1000.0 to before version 6.0.1698.0, a heap out-of-bounds read exists in the Android Verified Boot AVB vbmeta image parser in NanaZip via the upstream 7-Zip AvbHandler. An unsigned integer underflow in a...
