Categoría:	Mageia Linux Local Security Checks
Título:	Mageia: Security Advisory (MGASA-2022-0324)
Resumen:	The remote host is missing an update for the 'kernel, kmod-virtualbox, kmod-xtables-addons' package(s) announced via the MGASA-2022-0324 advisory.
Descripción:	Summary: The remote host is missing an update for the 'kernel, kmod-virtualbox, kmod-xtables-addons' package(s) announced via the MGASA-2022-0324 advisory. Vulnerability Insight: This kernel update is based on upstream 5.15.65 and fixes at least the following security issues: An out-of-bounds memory read flaw was found in the Linux kernel's BPF subsystem in how a user calls the bpf_tail_call function with a key larger than the max_entries of the map. This flaw allows a local user to gain unauthorized access to data (CVE-2022-2905). A race condition was found in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. This flaw could allow a local attacker to potentially trigger an out-of-bounds write or leak kernel heap memory by performing an out-of-bounds read and copying it into a socket (CVE-2022-3028). There exists a use-after-free in io_uring in the Linux kernel. Signalfd_poll() and binder_poll() use a waitqueue whose lifetime is the current task. It will send a POLLFREE notification to all waiters before the queue is freed. Unfortunately, the io_uring poll doesn't handle POLLFREE. This allows a use-after-free to occur if a signalfd or binder fd is polled with io_uring poll, and the waitqueue gets freed (CVE-2022-3176). An issue was discovered in net/netfilter/nf_tables_api.c in the kernel before 5.19.6. A denial of service can occur upon binding to an already bound chain (CVE-2022-39190). mm/rmap.c in the Linux kernel before 5.19.7 has a use-after-free related to leaf anon_vma double reuse (CVE-2022-42703). Other fixes in this update: - A fix for an issue causing excessive logging (mga#30779) due to an upstream change that was included in the 5.15.62 kernel update released as MGASA-2022-0305. - bpf, cgroup: Fix kernel BUG in purge_effective_progs - bpf: Restrict bpf_sys_bpf to CAP_PERFMON - Revert 'xhci: turn off port power in shutdown' as it causes some systems to hang on shutdown. For other upstream fixes in this update, see the referenced changelogs. Affected Software/OS: 'kernel, kmod-virtualbox, kmod-xtables-addons' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 6.8 CVSS Vector: AV:L/AC:L/Au:S/C:C/I:C/A:C
