CVE-2023-52576 – x86/mm, kexec, ima: Use memblock_free_late() from ima_free_kexec_buffer()
https://notcve.org/view.php?id=CVE-2023-52576
02 Mar 2024 — In the Linux kernel, the following vulnerability has been resolved: x86/mm, kexec, ima: Use memblock_free_late() from ima_free_kexec_buffer() The code calling ima_free_kexec_buffer() runs long after the memblock allocator has already been torn down, potentially resulting in a use after free in memblock_isolate_range(). With KASAN or KFENCE, this use after free will result in a BUG from the idle task, and a subsequent kernel panic. Switch ima_free_kexec_buffer() over to memblock_free_late() to avoid that bug... • https://git.kernel.org/stable/c/fee3ff99bc67604fba77f19da0106f3ec52b1956 • CWE-416: Use After Free •

02 Mar 2024 — In the Linux kernel, the following vulnerability has been resolved: btrfs: remove BUG() after failure to insert delayed dir index item Instead of calling BUG() when we fail to insert a delayed dir index item into the delayed node's tree, we can just release all the resources we have allocated/acquired before and return the error to the caller.

CVE-2023-52568 – x86/sgx: Resolves SECS reclaim vs. page fault for EAUG race
https://notcve.org/view.php?id=CVE-2023-52568
02 Mar 2024 — In the Linux kernel, the following vulnerability has been resolved: x86/sgx: Resolves SECS reclaim vs. page fault for EAUG race The SGX EPC reclaimer (ksgxd) may reclaim the SECS EPC page for an enclave and set secs.epc_page to NULL. The SECS page is used for EAUG and ELDU in the SGX page fault handler. However, the NULL check for secs.epc_page is only done for ELDU, not EAUG before being used. Fix this by doing the same NULL check and reloading of the SECS page as needed for both EAUG and ELDU. The SECS pa... • https://git.kernel.org/stable/c/5a90d2c3f5ef87717e54572af8426aba6fdbdaa6 •

02 Mar 2024 — In the Linux kernel, the following vulnerability has been resolved: serial: 8250_port: Check IRQ data before use In case the leaf driver wants to use IRQ polling (irq = 0) and IIR register shows that an interrupt happened in the 8250 hardware the IRQ data can be NULL.

CVE-2023-52566 – nilfs2: fix potential use after free in nilfs_gccache_submit_read_data()

02 Mar 2024 — In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix potential use after free in nilfs_gccache_submit_read_data() In nilfs_gccache_submit_read_data(), brelse(bh) is called to drop the reference count of bh when the call to nilfs_dat_translate() fails.
