kernel security update
An update for kernel is now available for openEuler-20.03-LTS-SP1, openEuler-20.03-LTS-SP3 and openEuler-22.03-LTS.
The Linux Kernel, the operating system core itself.
Security Fix(es):
A NULL pointer dereference flaw was found in the Linux kernel’s Amateur Radio AX.25 protocol functionality in the way a user connects with the protocol. This flaw allows a local user to crash the system.(CVE-2022-1205)
UAF causes the system to crash Exploit conditions: The root user reduces the reference count of drm_vgem_gem_object through ioctl$DRM_IOCTL_MODE_DESTROY_DUMB, and vgem_gem_dumb_create will access the released drm_vgem_gem_object Technical reason: The gpu driver can reduce the reference count of drm_vgem_gem_object through ioctl Concurrency causes uaf judgment method: CONFIG_DRM is not configured No circumvention measures are involved: none(CVE-2022-1419)
A concurrency use-after-free issue was discovered between reset_interrupt and floppy_end_request in the latest kernel version (5.17.5 for now). The root cause is that after deallocating current_req in floppy_end_request, reset_interrupt still holds the freed current_req->error_count and accesses it concurrently.(CVE-2022-1652)
An update for kernel is now available for openEuler-20.03-LTS-SP1, openEuler-20.03-LTS-SP3 and openEuler-22.03-LTS.
openEuler Security has rated this update as having a security impact of high. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
