Описание
In the Linux kernel, the following vulnerability has been resolved:
bpf: Properly mark live registers for indirect jumps
For a gotox rX instruction the rX register should be marked as used
in the compute_insn_live_regs() function. Fix this.
A flaw was found in the Linux kernel's Berkeley Packet Filter (BPF) subsystem. This vulnerability arises from the kernel's failure to correctly identify and mark active registers during indirect jump operations within the BPF program execution. An attacker could potentially exploit this to manipulate the kernel's state, leading to unexpected system behavior or a bypass of security controls, which may result in information disclosure.
Отчет
Red Hat acknowledges the upstream Linux kernel correction for «bpf» as described in COMMENT_ZERO. Fixes are delivered through standard kernel errata for supported products. Operational exposure depends on whether this subsystem or driver is active in your configuration.
