The Linux Kernel, the operating system core itself. Security Fix(es): In drivers/media/dvb-core/dmxdev.c in the Linux kernel through 5.19.10, there is a use-after-free caused by refcount races, affecting dvb_demux_open and dvb_dmxdev_release.(CVE-2022-41218) Guests can trigger deadlock in Linux netback driver T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] The patch for XSA-392 introduced another issue which might result in a deadlock when trying to free the SKB of a packet dropped due to the XSA-392 handling (CVE-2022-42328). Additionally when dropping packages for other reasons the same deadlock could occur in case of netpoll being active for the interface the xen-netback driver is connected to (CVE-2022-42329).(CVE-2022-42329) An issue was discovered in the Linux kernel through 5.16-rc6. malidp_crtc_reset in drivers/gpu/drm/arm/malidp_crtc.c lacks check of the return value of kzalloc() and will cause the null pointer dereference.(CVE-2022-3115) An update for kernel is now available for openEuler-20.03-LTS-SP1. openEuler Security has rated this update as having a security impact of medium.
