Chainguard: linux-desktop-7.2-bootc: security update to 7.2.7-r0

medium Tenable Self-Hosted Container Security Plugin ID 474733

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: bpf: Mark signal tracepoint siginfo
 arguments as scalar The signal_generate and signal_deliver tracepoints declare their info argument as a
 struct kernel_siginfo pointer. btf_ctx_access() therefore treats it as a trusted pointer for tp_btf
 programs. Signal delivery also uses SEND_SIG_NOINFO and SEND_SIG_PRIV as special values for this argument.
 Those values are zero and one respectively, and are not pointers. A tp_btf program can currently
 dereference either value and fault the kernel. In particular, signal_generate can run from timer interrupt
 context, turning the fault into a kernel panic. Record both tracepoints in raw_tp_null_args[] and mark
 argument one as a non-pointer. This preserves scalar access to the cookie while rejecting direct and
 helper-mediated pointer use. Merely marking it nullable would not suffice because SEND_SIG_PRIV is
 nonzero. (CVE-2026-98062)

Solution

Update the linux-desktop-7.2-bootc library and its related packages to version 7.2.7-r0 or later.
