A memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of service problem.

nfqnl_mangle in net/netfilter/nfnetlink_queue.c in the Linux kernel through 5.18.14 allows remote attackers to cause a denial of service (panic) because, in the case of an nf_queue verdict with a one-byte nfta_payload attribute, an skb_pull can encou...

An issue was discovered in the Linux kernel through 5.18.14. xfrm_expand_policies in net/xfrm/xfrm_policy.c can cause a refcount to be dropped twice.

A memory leak flaw was found in the Linux kernel in acrn_dev_ioctl in the drivers/virt/acrn/hsm.c function in how the ACRN Device Model emulates virtual NICs in VM. This flaw allows a local privileged attacker to leak unauthorized kernel information,...

A NULL pointer dereference flaw was found in rxrpc_preparse_s in net/rxrpc/server_key.c in the Linux kernel. This flaw allows a local attacker to crash the system or leak internal kernel information.

Rejected reason: DO NOT USE THIS CANDIDATE NUMBER. Reason: This CVE has been rejected as it was incorrectly assigned. All references and descriptions in this candidate have been removed to prevent accidental usage

When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of bounds.

Aliases in the branch predictor may cause some AMD processors to predict the wrong branch type potentially leading to information disclosure.

The Linux kernel was found vulnerable out of bounds memory access in the drivers/video/fbdev/sm712fb.c:smtcfb_read() function. The vulnerability could result in local attackers being able to crash the kernel.

Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions.
