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...
