In the Linux kernel, the following vulnerability has been resolved: bpf: Fix kernel address leakage in atomic fetch The change in commit 37086bfdc737 "bpf: Propagate stack bounds to registers in atomics w/ BPFFETCH" around checkmemaccess handling is buggy since this would allow for unprivileged...

SUSE CVE-2022-49873

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix wrong reg type conversion in releasereference Some helper functions will allocate memory. To avoid memory leaks, the verifier requires the eBPF program to release these memories by calling the corresponding helper...

kernel: uninitialized registers on stack in nft_do_chain can cause kernel pointer leakage to UM

A flaw was found in the Linux kernel in net/netfilter/nftablescore.c:nftdochain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker...

CVE-2018-7755

An issue was discovered in the fdlockedioctl function in drivers/block/floppy.c in the Linux kernel through 4.15.7. The floppy driver will copy a kernel pointer to user memory in response to the FDGETPRM ioctl. An attacker can send the FDGETPRM ioctl and use the obtained kernel pointer to discove...
