CVE-2026-43078 (GCVE-0-2026-43078)

Vulnerability from cvelistv5 – Published: 2026-05-06 07:40 – Updated: 2026-08-05 12:25

Title

crypto: af_alg - Fix page reassignment overflow in af_alg_pull_tsgl

Summary

In the Linux kernel, the following vulnerability has been resolved: crypto: af_alg - Fix page reassignment overflow in af_alg_pull_tsgl When page reassignment was added to af_alg_pull_tsgl the original loop wasn't updated so it may try to reassign one more page than necessary. Add the check to the reassignment so that this does not happen. Also update the comment which still refers to the obsolete offset argument.

Severity

7.8 (High)

No race or external timing condition is required.\nPR:L - Creating and using PF_ALG sockets for userspace crypto does not require real root or administrative capabilities. A basic unprivileged local user can reach the affected code.\nUI:N - Exploitation only requires attacker-issued syscalls on the attacker\u0027s own AF_ALG socket. No victim action is needed.\nS:U - The corruption occurs inside the kernel and impacts the same kernel security authority. This is standard local kernel attack surface rather than a VM or hardware boundary escape.\nC:H - The bug is kernel heap memory corruption immediately past an allocated scatterlist object. Following the higher-severity rule, this can plausibly be leveraged for kernel memory disclosure.\nI:H - The pre-fix code writes a scatterlist entry past the allocated destination array via sg_set_page. This is an out-of-bounds kernel heap write and can plausibly support privilege escalation or control-flow/object corruption.\nA:H - The issue is directly observed as a KASAN slab-out-of-bounds crash in af_alg_pull_tsgl from recvmsg. Repeated triggering can crash or destabilize the kernel."

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
