CVE-2022-50841

The CVE covers a Linux kernel NTFS3 parsing flaw: when parsing MFT attributes, an overflow in the attribute size calculation could let Add2Ptr(attr, asize) exceed bounds, enabling an out-of-bounds memory R/W. The issue has been mitigated by adding an overflow check for attribute sizes in fs/ntfs3...

In the Linux kernel, the following vulnerability has been resolved: jbd2: fix potential buffer head reference count leak As in 'jbd2fcwaitbufs' if buffer isn't uptodate, will return -EIO without update 'journal-jfcoff'. But 'jbd2fcreleasebufs' will release buffer head from ‘jfcoff - 1’ if 'bh' is...

CVE-2022-50828

CVE-2022-50828 affects the Linux kernel clock driver for ZynqMP (clk: zynqmp). The issue caused a stack-out-of-bounds access in strncpy during probe-time when the clock name exceeds 15 bytes, leading to a missing NUL terminator in the 16-byte SMC payload path used by Linux-ATF. The KSAN violation...
