In the Linux kernel, the following vulnerability has been resolved: Bluetooth: virtiobt: validate rx pkttype header length virtbtrxhandle reads the leading pkttype byte from the RX skb and forwards the remainder to hcirecvframe for every event/ACL/SCO/ISO type, without checking that the remaining...

Linux Kernel Security Vulnerabilities

The Linux kernel version 7.1 contains a security vulnerability. This vulnerability stems from the use of the TCP header length incorrectly in UDP GSO packets by the gvecansendtso function. This leads to an incorrect estimation of the number of segmentation buffers, potentially causing unnecessary...

CVE-2026-98288

The Linux kernel contains a vulnerability in the stmmac driver where stmmac_tso_xmit() incorrectly stores the protocol header length in a u8 variable. Because stmmac_tso_valid_packet() allows headers up to 1023 bytes, any header exceeding 255 bytes—such as a TCP over IPv6 socket with specific des...

CVE-2026-65979

A flaw was found in OpenEXR's HTJ2K decoder. A local user could be tricked into opening a specially crafted EXR image file. When processed, the decoder reads beyond the bounds of an allocated buffer due to an unvalidated header length field. This out-of-bounds read can lead to a denial of service...
