CVE-2023-53576 null_blk: Always check queue mode setting from configfs

In the Linux kernel, the following vulnerability has been resolved: nullblk: Always check queue mode setting from configfs Make sure to check device queue mode in the nullvalidateconf and return error for NULLQRQ as we don't allow legacy I/O path, without this patch we get OOPs when queue mode is...

CVE-2023-53576

CVE-2023-53576 affects the Linux kernel’s null_blk driver. The patch ensures queue mode is always validated from configfs by checking queue_mode in null_validate_conf() and returning an error for NULL_Q_RQ to prevent a NULL I/O path OOPs when queue_mode is set to 1. Reproduction steps are provide...

CVE-2023-53569

The CVE-2023-53569 entry refers to the Linux kernel ext2 filesystem check during mount, where the log of the block size stored in the superblock must be validated to prevent an overflow in the block size calculation. This vulnerability can cause undefined behavior if the block size value is not s...

CVE-2023-53569 ext2: Check block size validity during mount

In the Linux kernel, the following vulnerability has been resolved: ext2: Check block size validity during mount Check that log of block size stored in the superblock has sensible value. Otherwise the shift computing the block size can overflow leading to undefined behavior...

CVE-2023-53536 blk-crypto: make blk_crypto_evict_key() more robust

In the Linux kernel, the following vulnerability has been resolved: blk-crypto: make blkcryptoevictkey more robust If blkcryptoevictkey sees that the key is still in-use due to a bug or that -keyslotevict failed, it currently just returns while leaving the key linked into the keyslot management...

CVE-2023-53536

CVE-2023-53536 affects the Linux kernel in the blk-crypto subsystem. The issue stems from blk_crypto_evict_key() sometimes returning early without unlinking the key from the keyslot management structures, while the caller proceeds to free the blk_crypto_key. This mismatch can cause a use-after-fr...

CVE-2022-50484

CVE-2022-50484 affects the Linux kernel ALSA USB audio driver. The vulnerability is a memory leak when -ENOMEM occurs during URB/buffer allocation inside the sync EP URB loop, where ep->nurbs remained 0 and partially allocated URBs could be left unreleased. The fix initializes ep->nurbs ear...
