USN-5384-1: Linux kernel vulnerabilities It was discovered that the UDF file system implementation in the Linux kernel could attempt to dereference a null pointer in some situations. An attacker could use this to construct a malicious UDF image that, when mounted and operated on, could cause a denial of service (system crash). (CVE-2022-0617) Lyu Tao discovered that the NFS implementation in the Linux kernel did not properly handle requests to open a directory on a regular file. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-24448) It was discovered that the YAM AX.25 device driver in the Linux kernel did not properly deallocate memory in some error conditions. A local privileged attacker could use this to cause a denial of service (kernel memory exhaustion). (CVE-2022-24959) Source: USN-5384-1: Linux kernel vulnerabilities

USN-5383-1: Linux kernel vulnerabilities David Bouman discovered that the netfilter subsystem in the Linux kernel did not properly validate passed user register indices. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2022-1015) Brendan Dolan-Gavitt discovered that the Marvell WiFi-Ex USB device driver in the Linux kernel did not properly handle some error conditions. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2021-43976) Wenqing Liu discovered that the f2fs file system implementation in the Linux kernel did not properly validate inode types while performing garbage collection. An attacker could use this to construct a malicious f2fs image that, when mounted and operated on, could cause a denial of service (system crash). (CVE-2021-44879) It was discovered that the UDF file system implementation in the Linux kernel [ more… ]

USN-5382-1: libinput vulnerability Albin Eldstål-Ahrens and Lukas Lamster discovered libinput did not properly handle input devices with specially crafted names. A local attacker with physical access could use this to cause libinput to crash or expose sensitive information. Source: USN-5382-1: libinput vulnerability

USN-5381-1: Linux kernel (OEM) vulnerabilities David Bouman discovered that the netfilter subsystem in the Linux kernel did not properly validate passed user register indices. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2022-1015) It was discovered that the block layer subsystem in the Linux kernel did not properly initialize memory in some situations. A privileged local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-0494) It was discovered that the DMA subsystem in the Linux kernel did not properly ensure bounce buffers were completely overwritten by the DMA device. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-0854) Jann Horn discovered that the FUSE file system in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of [ more… ]
