|---|---|---|---|
| 2024-12-27 | CVE-2024-53170 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: block: fix uaf for flush rq while iterating tags blk_mq_clear_flush_rq_mapping() is not called during scsi probe, by checking blk_queue_init_done(). | 7.8 |
| 2024-12-27 | CVE-2024-53171 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ubifs: authentication: Fix use-after-free in ubifs_tnc_end_commit After an insertion in TNC, the tree might split and cause a node to change its `znode->parent`. | 7.8 |
| 2024-12-27 | CVE-2024-53173 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: NFSv4.0: Fix a use-after-free problem in the asynchronous open() Yang Erkun reports that when two threads are opening files at the same time, and are forced to abort before a reply is seen, then the call to nfs_release_seqid() in nfs4_opendata_free() can result in a use-after-free of the pointer to the defunct rpc task of the other thread. The fix is to ensure that if the RPC call is aborted before the call to nfs_wait_on_sequence() is complete, then we must call nfs_release_seqid() in nfs4_open_release() before the rpc_task is freed. | 7.8 |
| 2024-12-27 | CVE-2024-53179 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: smb: client: fix use-after-free of signing key Customers have reported use-after-free in @ses->auth_key.response with SMB2.1 + sign mounts which occurs due to following race: task A task B cifs_mount() dfs_mount_share() get_session() cifs_mount_get_session() cifs_send_recv() cifs_get_smb_ses() compound_send_recv() cifs_setup_session() smb2_setup_request() kfree_sensitive() smb2_calc_signature() crypto_shash_setkey() *UAF* Fix this by ensuring that we have a valid @ses->auth_key.response by checking whether @ses->ses_status is SES_GOOD or SES_EXITING with @ses->ses_lock held. | 7.8 |
| 2024-12-27 | CVE-2024-53180 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Add sanity NULL check for the default mmap fault handler A driver might allow the mmap access before initializing its runtime->dma_area properly. | 5.5 |

| 2024-12-27 | CVE-2024-53210 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: s390/iucv: MSG_PEEK causes memory leak in iucv_sock_destruct() Passing MSG_PEEK flag to skb_recv_datagram() increments skb refcount (skb->users) and iucv_sock_recvmsg() does not decrement skb refcount at exit. This results in skb memory leak in skb_queue_purge() and WARN_ON in iucv_sock_destruct() during socket close. | 5.5 |
