Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: AppArmor: Avoid per-cpu hold underflow in aagetbuffer. When aagetbuffer retrieves data from the per-cpu list, it conditionally decreases cache-hold. If hold reaches 0 while count remains non-zero, the unsigned decrement wraps to...

Astra Linux – Vulnerability in libexif

In libexif versions up to 0.6.25, a integer underflow in size checking for Fuji and Olympus MakerNote decoding could be exploited by attackers to cause programs that use libexif to crash or leak information...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.0, there was an integer underflow issue in the updatereadcachebitmaporder function of FreeRDP’s core library. This vulnerability has been fixed in version 3.24.0...

Astra Linux – Vulnerability in freerdp3

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.0, a underflow of the sizet variable in the IMA-ADPCM and MS-ADPCM audio decoders led to a heap-buffer-overflow issue through the RDPSND audio channel. In libfreerdp/codec/dsp.c, the IMA-ADPCM and MS-ADPCM...

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...

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 Capstone

Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and earlier, a unchecked return from vsnprintf in SStreamconcat allowed a malicious csoptmem.vsnprintf to manipulate SStream’s index beyond its limit, resulting in a stack buffer underflow/overflow when the next write operation occurre...

CVE-2026-52919

CVE-2026-52919 affects the batman-adv component in the Linux kernel. The root cause is an underflow of the atomic counter “sending” in batadv_tp_sender_shutdown(), which is decremented unconditionally and can become -1 when multiple code paths call it. A negative value causes the sender kthread t...
