| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 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-2024-40932 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/exynos/vidi: fix memory leak in .get_modes() The duplicated EDID is never freed. | 5.5 |
| 2024-07-12 | CVE-2024-40965 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: i2c: lpi2c: Avoid calling clk_get_rate during transfer Instead of repeatedly calling clk_get_rate for each transfer, lock the clock rate and cache the value. A deadlock has been observed while adding tlv320aic32x4 audio codec to the system. | 5.5 |
| 2024-07-12 | CVE-2024-40967 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: serial: imx: Introduce timeout when waiting on transmitter empty By waiting at most 1 second for USR2_TXDC to be set, we avoid a potential deadlock. In case of the timeout, there is not much we can do, so we simply ignore the transmitter state and optimistically try to continue. | 5.5 |
| 2024-07-12 | CVE-2024-40969 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: f2fs: don't set RO when shutting down f2fs Shutdown does not check the error of thaw_super due to readonly, which causes a deadlock like below. f2fs_ioc_shutdown(F2FS_GOING_DOWN_FULLSYNC) issue_discard_thread - bdev_freeze - freeze_super - f2fs_stop_checkpoint() - f2fs_handle_critical_error - sb_start_write - set RO - waiting - bdev_thaw - thaw_super_locked - return -EINVAL, if sb_rdonly() - f2fs_stop_discard_thread -> wait for kthread_stop(discard_thread); | 5.5 |
| 2024-07-12 | CVE-2024-40970 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Avoid hw_desc array overrun in dw-axi-dmac I have a use case where nr_buffers = 3 and in which each descriptor is composed by 3 segments, resulting in the DMA channel descs_allocated to be 9. | 5.5 |
| 2024-07-12 | CVE-2024-40973 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: mtk-vcodec: potential null pointer deference in SCP The return value of devm_kzalloc() needs to be checked to avoid NULL pointer deference. | 5.5 |
