CVE-2026-53004

Summary of CVE-2026-53004 : In the Linux kernel, sctp_getsockopt_peer_auth_chunks can perform an out-of-bounds write to user space when the caller provides a short optval buffer. The check tests len vs num_chunks but forgets to account for sizeof(struct sctp_authchunks) header (8 bytes), allowing...

GHSA-RR89-W3H9-M66J ExifReader is vulnerable to denial of service via unbounded decompression of image metadata

Impact Versions of ExifReader from 4.20.0 through 4.38.1 do not bound the size of decompressed metadata blocks. When a caller invokes the asynchronous API e.g. ExifReader.loadfile or ExifReader.loadbuffer, async: true on an attacker-supplied image, a small compressed chunk in the file can expand ...
