In the Linux kernel, the following vulnerability has been resolved: bpf: Avoid soft lockup in htab map lookup and delete batch htab map lookup and delete batch has no rescheduling point. The batch count bounds how many entries are copied out, not how many buckets are visited, so one BPF MAP LOOKU...

CVE-2023-53790

CVE-2023-53790 : In the Linux kernel BPF memory allocator, freed elements may be reused immediately. For htab maps, reusing a value reinitializes special fields (e.g., bpf_spin_lock) but the lookup path may still access these fields, potentially causing a hard lockup. The fix is to initialize the...

PT-2025-49650

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.1.0+ 1 Description The Linux kernel contains an issue in the bpf memory allocator where a freed element may be immediately reused. For htab maps, this reuse can reinitialize special fields in map values, but...

Linux kernel BPF Heap Buffer Overflow DoS

The vulnerability of the htabmapalloc function in the kernel/bpf/hashtab.c module of the Linux operating system’s BPF subsystem in 32-bit architectures is related to integer overflow. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...
