Category:	Mageia Linux Local Security Checks
Title:	Mageia: Security Advisory (MGASA-2021-0367)
Summary:	The remote host is missing an update for the 'kernel-linus' package(s) announced via the MGASA-2021-0367 advisory.
Description:	Summary: The remote host is missing an update for the 'kernel-linus' package(s) announced via the MGASA-2021-0367 advisory. Vulnerability Insight: This kernel-linus update is based on upstream 5.10.52 and fixes at least the following security issues: There is a race condition in net/can/bcm.c that can lead to local privilege escalation to root (CVE-2021-3609). A vulnerability was found in the Linux kernel. Missing size validations on inbound SCTP packets may allow the kernel to read uninitialized memory (CVE-2021-3655). fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does not properly restrict seq buffer allocations, leading to an integer overflow, an Out-of-bounds Write, and escalation to root by an unprivileged user (CVE-2021-33909). For other upstream fixes, see the referenced changelogs. Affected Software/OS: 'kernel-linus' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
