CVE-2026-98631

In the Linux kernel, the following vulnerability has been resolved: xsk: Use a 32-bit compare in xskmapgenlookup xskmapgenlookup loads a u32 key and compares it with maxentries using BPFJMPIMM. BPF immediates are sign-extended to 64 bits, so a maxentries value of 0x80000000 or higher becomes a...

CVE-2026-98631

The Linux kernel contains a vulnerability in the xsk component within the xsk_map_gen_lookup() function. The root cause is the use of BPF_JMP_IMM to compare a 32-bit key against max_entries. Because BPF immediates are sign-extended to 64 bits, a max_entries value of 0x80000000 or higher creates a...
