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: Skip unsettled links in link
 iterator bpf_link_prime() inserts a link into link_idr before anon_inode_getfile() succeeds and before
 bpf_link_settle() publishes the ID in link->id. bpf_link_by_id() treats such an ID-zero link as unsettled,
 but the link iterator takes a reference without this check. If anon_inode_getfile() then fails, the
 creator removes the ID and frees its still-private link directly. The iterator is left with a dangling
 reference and its next bpf_link_put() accesses freed memory. Treat ID-zero entries as transient in
 bpf_link_get_curr_or_next(), just as bpf_link_by_id() does. BUG: KASAN: slab-use-after-free in
 bpf_link_put Write of size 8 by task exp/384 Call Trace: bpf_link_put kernel/bpf/syscall.c:3372
 bpf_link_seq_next kernel/bpf/link_iter.c:33 bpf_seq_read kernel/bpf/bpf_iter.c:158 vfs_read
 fs/read_write.c:572 ksys_read fs/read_write.c:716 do_syscall_64 arch/x86/entry/syscall_64.c:84
 entry_SYSCALL_64_after_hwframe arch/x86/entry/entry_64.S:121 Kernel panic - not syncing: KASAN:
 panic_on_warn set ... (CVE-2026-98378)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.739.5 or later.
