USN-6052-1: Linux kernel vulnerability It was discovered that the Traffic-Control Index (TCINDEX) implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for this CVE, kernel support for the TCINDEX classifier has been removed.

USN-6051-1: Linux kernel vulnerabilities It was discovered that the Traffic-Control Index (TCINDEX) implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for this CVE, kernel support for the TCINDEX classifier has been removed. (CVE-2023-1829) It was discovered that a race condition existed in the io_uring subsystem in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-1872) Source: USN-6051-1: Linux kernel vulnerabilities
USN-6050-1: Git vulnerabilities It was discovered that Git incorrectly handled certain commands. An attacker could possibly use this issue to overwriting some paths. (CVE-2023-25652) Maxime Escourbiac and Yassine BENGANA discovered that Git incorrectly handled some gettext machinery. An attacker could possibly use this issue to allows the malicious placement of crafted messages. (CVE-2023-25815) André Baptista and Vítor Pinho discovered that Git incorrectly handled certain configurations. An attacker could possibly use this issue to arbitrary configuration injection.
