https://notcve.org/view.php?id=CVE-2024-41062
In the Linux kernel, the following vulnerability has been resolved: bluetooth/l2cap: sync sock recv cb and release The problem occurs between the system call to close the sock and hci_rx_work, where the former releases the sock and the latter accesses it without lock protection. CPU0 CPU1 ---- ---- sock_close hci_rx_work l2cap_sock_release hci_acldata_packet l2cap_sock_kill l2cap_recv_frame sk_free l2cap_conless_channel l2cap_sock_recv_cb If hci_rx_work processes the data that needs to be received before the sock is closed, then everything is normal; Otherwise, the work thread may access the released sock when receiving data. Add a chan mutex in the rx callback of the sock to achieve synchronization between the sock release and recv cb. Sock is dead, so set chan data to NULL, avoid others use invalid sock pointer. • https://git.kernel.org/stable/c/605572e64cd9cebb05ed609d96cff05b50d18cdf https://git.kernel.org/stable/c/b803f30ea23e0968b6c8285c42adf0d862ab2bf6 https://git.kernel.org/stable/c/3b732449b78183d17178db40be3a4401cf3cd629 https://git.kernel.org/stable/c/89e856e124f9ae548572c56b1b70c2255705f8fe •

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix array-index-out-of-bounds in dml2/FCLKChangeSupport [Why] Potential out of bounds access in dml2_calculate_rq_and_dlg_params() because the value of out_lowest_state_idx used as an index for FCLKChangeSupport array can be greater than 1. [How] Currently dml2 core specifies identical values for all FCLKChangeSupport elements. Always use index 0 in the condition to avoid out of bounds access. • https://git.kernel.org/stable/c/94166fe12543fbef122ca2d093e794ea41073a85 https://git.kernel.org/stable/c/0ad4b4a2f6357c45fbe444ead1a929a0b4017d03 •

In the Linux kernel, the following vulnerability has been resolved: mm: prevent derefencing NULL ptr in pfn_section_valid() Commit 5ec8e8ea8b77 ("mm/sparsemem: fix race in accessing memory_section->usage") changed pfn_section_valid() to add a READ_ONCE() call around "ms->usage" to fix a race with section_deactivate() where ms->usage can be cleared. The READ_ONCE() call, by itself, is not enough to prevent NULL pointer dereference. We need to check its value before dereferencing it. • https://git.kernel.org/stable/c/90ad17575d26874287271127d43ef3c2af876cea https://git.kernel.org/stable/c/b448de2459b6d62a53892487ab18b7d823ff0529 https://git.kernel.org/stable/c/68ed9e33324021e9d6b798e9db00ca3093d2012a https://git.kernel.org/stable/c/70064241f2229f7ba7b9599a98f68d9142e81a97 https://git.kernel.org/stable/c/5ec8e8ea8b7783fab150cf86404fc38cb4db8800 https://git.kernel.org/stable/c/3a01daace71b521563c38bbbf874e14c3e58adb7 https://git.kernel.org/stable/c/0100aeb8a12d51950418e685f879cc80cb8e5982 https://git.kernel.org/stable/c/bc17f2377818dca643a74499c3f533350 • CWE-476: NULL Pointer Dereference •
