A use-after-free vulnerability was found in the Linux kernel's fsl-usb phy driver. The vulnerability occurs when the device is removed while a delayed work item is still pending or executing, leading to a use-after-free error when the work function accesses the already freed memory. The issue was resolved by calling disable_delayed_work_sync() in fsl_otg_remove() before deallocating the fsl_otg structure.
A vulnerability in the Linux kernel's handshake mechanism could lead to a reference count underflow when duplicate cancellation requests are made for the same handshake. This issue arises because the handshake request is removed from the handshake_net->hn_requests list but remains in the handshake_rhashtbl until it is destroyed. If a second cancellation request is made, remove_pending() returns false, and [truncated]
A race condition vulnerability in the Linux kernel's hfsplus filesystem implementation can lead to a use-after-free bug. When sync() and link() are called concurrently, both threads may enter hfs_bnode_find() without finding the node in the hash table and proceed to create it. However, hfs_bnode_find() requires each call to take a reference. In this scenario, the second thread finds the node in the hash t [truncated]
