|---|---|---|---|
| 2024-07-14 | CVE-2023-52885 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Fix UAF in svc_tcp_listen_data_ready() After the listener svc_sock is freed, and before invoking svc_tcp_accept() for the established child sock, there is a window that the newsock retaining a freed listener svc_sock in sk_user_data which cloning from parent. | 7.8 |
| 2024-07-12 | CVE-2024-39494 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ima: Fix use-after-free on a dentry's dname.name ->d_name.name can change on rename and the earlier value can be freed; there are conditions sufficient to stabilize it (->d_lock on dentry, ->d_lock on its parent, ->i_rwsem exclusive on the parent's inode, rename_lock), but none of those are met at any of the sites. | 7.8 |
| 2024-07-12 | CVE-2024-39495 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: greybus: Fix use-after-free bug in gb_interface_release due to race condition. In gb_interface_create, &intf->mode_switch_completion is bound with gb_interface_mode_switch_work. | 7.8 |
| 2024-07-12 | CVE-2024-39496 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: btrfs: zoned: fix use-after-free due to race with dev replace While loading a zone's info during creation of a block group, we can race with a device replace operation and then trigger a use-after-free on the device that was just replaced (source device of the replace operation). This happens because at btrfs_load_zone_info() we extract a device from the chunk map into a local variable and then use the device while not under the protection of the device replace rwsem. | 7.8 |
| 2024-07-12 | CVE-2024-40902 | Classic Buffer Overflow vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: jfs: xattr: fix buffer overflow for invalid xattr When an xattr size is not what is expected, it is printed out to the kernel log in hex format as a form of debugging. | 7.8 |
| 2024-07-12 | CVE-2024-40904 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: USB: class: cdc-wdm: Fix CPU lockup caused by excessive log messages The syzbot fuzzer found that the interrupt-URB completion callback in the cdc-wdm driver was taking too long, and the driver's immediate resubmission of interrupt URBs with -EPROTO status combined with the dummy-hcd emulation to cause a CPU lockup: cdc_wdm 1-1:1.0: nonzero urb status received: -71 cdc_wdm 1-1:1.0: wdm_int_callback - 0 bytes watchdog: BUG: soft lockup - CPU#0 stuck for 26s!

In any case, the best approach for preventing these lockups and to avoid spamming the log with thousands of error messages per second is to ratelimit the two dev_err() calls. | 5.5 |
| 2024-07-12 | CVE-2024-40905 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ipv6: fix possible race in __fib6_drop_pcpu_from() syzbot found a race in __fib6_drop_pcpu_from() [1] If compiler reads more than once (*ppcpu_rt), second read could read NULL, if another cpu clears the value in rt6_get_pcpu_route(). Add a READ_ONCE() to prevent this race. Also add rcu_read_lock()/rcu_read_unlock() because we rely on RCU protection while dereferencing pcpu_rt.
