| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-02-27 | CVE-2021-46926 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ALSA: hda: intel-sdw-acpi: harden detection of controller The existing code currently sets a pointer to an ACPI handle before checking that it's actually a SoundWire controller. | 5.5 |
| 2024-02-27 | CVE-2021-46928 | Improper Handling of Exceptional Conditions vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: parisc: Clear stale IIR value on instruction access rights trap When a trap 7 (Instruction access rights) occurs, this means the CPU couldn't execute an instruction due to missing execute permissions on the memory region. | 5.5 |
| 2024-02-26 | CVE-2019-25160 | Out-of-bounds Read vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: netlabel: fix out-of-bounds memory accesses There are two array out-of-bounds memory accesses, one in cipso_v4_map_lvl_valid(), the other in netlbl_bitmap_walk(). | 7.1 |
| 2024-02-26 | CVE-2020-36775 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to avoid potential deadlock Using f2fs_trylock_op() in f2fs_write_compressed_pages() to avoid potential deadlock like we did in f2fs_write_single_data_page(). | 5.5 |
| 2024-02-26 | CVE-2021-46906 | Exposure of Resource to Wrong Sphere vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: HID: usbhid: fix info leak in hid_submit_ctrl In hid_submit_ctrl(), the way of calculating the report length doesn't take into account that report->size can be zero. | 5.5 |
| 2024-02-26 | CVE-2024-26601 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ext4: regenerate buddy after block freeing failed if under fc replay This mostly reverts commit 6bd97bf273bd ("ext4: remove redundant mb_regenerate_buddy()") and reintroduces mb_regenerate_buddy(). | 5.5 |
| 2024-02-23 | CVE-2024-26598 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic-its: Avoid potential UAF in LPI translation cache There is a potential UAF scenario in the case of an LPI translation cache hit racing with an operation that invalidates the cache, such as a DISCARD ITS command. | 7.8 |
| 2024-02-22 | CVE-2023-52443 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: apparmor: avoid crash when parsed profile name is empty When processing a packed profile in unpack_profile() described like "profile :ns::samba-dcerpcd /usr/lib*/samba/{,samba/}samba-dcerpcd {...}" a string ":samba-dcerpcd" is unpacked as a fully-qualified name and then passed to aa_splitn_fqname(). aa_splitn_fqname() treats ":samba-dcerpcd" as only containing a namespace. Thus it returns NULL for tmpname, meanwhile tmpns is non-NULL. | 5.5 |
| 2024-02-22 | CVE-2023-52445 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: pvrusb2: fix use after free on context disconnection Upon module load, a kthread is created targeting the pvr2_context_thread_func function, which may call pvr2_context_destroy and thus call kfree() on the context object. | 7.8 |
| 2024-02-22 | CVE-2024-26587 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: netdevsim: don't try to destroy PHC on VFs PHC gets initialized in nsim_init_netdevsim(), which is only called if (nsim_dev_port_is_pf()). Create a counterpart of nsim_init_netdevsim() and move the mock_phc_destroy() there. This fixes a crash trying to destroy netdevsim with VFs instantiated, as caught by running the devlink.sh test: BUG: kernel NULL pointer dereference, address: 00000000000000b8 RIP: 0010:mock_phc_destroy+0xd/0x30 Call Trace: <TASK> nsim_destroy+0x4a/0x70 [netdevsim] __nsim_dev_port_del+0x47/0x70 [netdevsim] nsim_dev_reload_destroy+0x105/0x120 [netdevsim] nsim_drv_remove+0x2f/0xb0 [netdevsim] device_release_driver_internal+0x1a1/0x210 bus_remove_device+0xd5/0x120 device_del+0x159/0x490 device_unregister+0x12/0x30 del_device_store+0x11a/0x1a0 [netdevsim] kernfs_fop_write_iter+0x130/0x1d0 vfs_write+0x30b/0x4b0 ksys_write+0x69/0xf0 do_syscall_64+0xcc/0x1e0 entry_SYSCALL_64_after_hwframe+0x6f/0x77 | 5.5 |
