USN-5210-2: Linux kernel regression

USN-5210-1 fixed vulnerabilities in the Linux kernel. Unfortunately, that update introduced a regression that caused failures to boot in environments with AMD Secure Encrypted Virtualization SEV enabled. This update fixes the problem. We apologize for the inconvenience. Original advisory details:...

USN-5165-1: Linux kernel (OEM) vulnerabilities

It was discovered that the NFC subsystem in the Linux kernel contained a use-after-free vulnerability in its NFC Controller Interface NCI implementation. A local attacker could possibly use this to cause a denial of service system crash or execute arbitrary code. CVE-2021-3760 It was discovered...

The vulnerability of the `detach_capi_ctr` function in the driver `/isdn/capi/kcapi.c` of Linux operating system kernels allows a hacker to cause a service failure.

The vulnerability of the detachcapictr function in the /isdn/capi/kcapi.c driver of Linux operating systems is related to errors in array indexing, which can lead to reading beyond the buffer in memory. Exploiting this vulnerability can allow an attacker to cause service failures...
