| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-12-27 | CVE-2024-56602 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: ieee802154: do not leave a dangling sk pointer in ieee802154_create() sock_init_data() attaches the allocated sk object to the provided sock object. | 7.8 |
| 2024-12-27 | CVE-2024-56603 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: af_can: do not leave a dangling sk pointer in can_create() On error can_create() frees the allocated sk object, but sock_init_data() has already attached it to the provided sock object. | 7.8 |
| 2024-12-27 | CVE-2024-56604 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: avoid leaving dangling sk pointer in rfcomm_sock_alloc() bt_sock_alloc() attaches allocated sk object to the provided sock object. If rfcomm_dlc_alloc() fails, we release the sk object, but leave the dangling pointer in the sock object, which may cause use-after-free. Fix this by swapping calls to bt_sock_alloc() and rfcomm_dlc_alloc(). | 7.8 |
| 2024-12-27 | CVE-2024-56605 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: do not leave dangling sk pointer on error in l2cap_sock_create() bt_sock_alloc() allocates the sk object and attaches it to the provided sock object. | 7.8 |
| 2024-12-27 | CVE-2024-56606 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: af_packet: avoid erroring out after sock_init_data() in packet_create() After sock_init_data() the allocated sk object is attached to the provided sock object. | 7.8 |
| 2024-12-27 | CVE-2024-56608 | Improper Validation of Array Index vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix out-of-bounds access in 'dcn21_link_encoder_create' An issue was identified in the dcn21_link_encoder_create function where an out-of-bounds access could occur when the hpd_source index was used to reference the link_enc_hpd_regs array. | 7.8 |
| 2024-12-27 | CVE-2024-56611 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mm/mempolicy: fix migrate_to_node() assuming there is at least one VMA in a MM We currently assume that there is at least one VMA in a MM, which isn't true. So we might end up having find_vma() return NULL, to then de-reference NULL. | 5.5 |
| 2024-12-27 | CVE-2024-56623 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix use after free on unload System crash is observed with stack trace warning of use after free. | 5.5 |
| 2024-12-27 | CVE-2024-56659 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: lapb: increase LAPB_HEADER_LEN It is unclear if net/lapb code is supposed to be ready for 8021q. We can at least avoid crashes like the following : skbuff: skb_under_panic: text:ffffffff8aabe1f6 len:24 put:20 head:ffff88802824a400 data:ffff88802824a3fe tail:0x16 end:0x140 dev:nr0.2 ------------[ cut here ]------------ kernel BUG at net/core/skbuff.c:206 !

| 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 |
