A flaw was found in btrfs_get_root_ref in fs/btrfs/disk-io.c in the btrfs filesystem in the Linux Kernel due to a double decrement of the reference count. This issue may allow a local attacker with user privilege to crash the system or may lead to le...

A NULL pointer dereference flaw was found in dbFree in fs/jfs/jfs_dmap.c in the journaling file system (JFS) in the Linux Kernel. This issue may allow a local attacker to crash the system due to a missing sanity check.

An issue was discovered in l2cap_sock_release in net/bluetooth/l2cap_sock.c in the Linux kernel before 6.4.10. There is a use-after-free because the children of an sk are mishandled.

Improper access control in the Intel(R) Ethernet Controller RDMA driver for linux before version 1.9.30 may allow an unauthenticated user to potentially enable escalation of privilege via network access.

Information exposure through microarchitectural state after transient execution in certain vector execution units for some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

A flaw was found in the exFAT driver of the Linux kernel. The vulnerability exists in the implementation of the file name reconstruction function, which is responsible for reading file name entries from a directory index and merging file name parts b...

A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address prediction. This may result in speculative execution at an attacker-controlled address, potentially leading to information disclosure. ...

A division-by-zero error on some AMD processors can potentially return speculative data resulting in loss of confidentiality. 

A use-after-free flaw was found in the Linux kernel’s Netfilter functionality when adding a rule with NFTA_RULE_CHAIN_ID. This flaw allows a local user to crash or escalate their privileges on the system.
