| 2024-10-21 | CVE-2024-50003 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix system hang while resume with TBT monitor [Why] Connected with a Thunderbolt monitor and do the suspend and the system may hang while resume. The TBT monitor HPD will be triggered during the resume procedure and call the drm_client_modeset_probe() while struct drm_connector connector->dev->master is NULL. It will mess up the pipe topology after resume. [How] Skip the TBT monitor HPD during the resume procedure because we currently will probe the connectors after resume by default. (cherry picked from commit 453f86a26945207a16b8f66aaed5962dc2b95b85) | 5.5 |
| 2024-10-21 | CVE-2024-50004 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: update DML2 policy EnhancedPrefetchScheduleAccelerationFinal DCN35 [WHY & HOW] Mismatch in DCN35 DML2 cause bw validation failed to acquire unexpected DPP pipe to cause grey screen and system hang. | 5.5 |
| 2024-10-21 | CVE-2024-50006 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ext4: fix i_data_sem unlock order in ext4_ind_migrate() Fuzzing reports a possible deadlock in jbd2_log_wait_commit. This issue is triggered when an EXT4_IOC_MIGRATE ioctl is set to require synchronous updates because the file descriptor is opened with O_SYNC. This can lead to the jbd2_journal_stop() function calling jbd2_might_wait_for_commit(), potentially causing a deadlock if the EXT4_IOC_MIGRATE call races with a write(2) system call. This problem only arises when CONFIG_PROVE_LOCKING is enabled. | 4.7 |
| 2024-10-21 | CVE-2024-50008 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: wifi: mwifiex: Fix memcpy() field-spanning write warning in mwifiex_cmd_802_11_scan_ext() Replace one-element array with a flexible-array member in `struct host_cmd_ds_802_11_scan_ext`. With this, fix the following warning: elo 16 17:51:58 surfacebook kernel: ------------[ cut here ]------------ elo 16 17:51:58 surfacebook kernel: memcpy: detected field-spanning write (size 243) of single field "ext_scan->tlv_buffer" at drivers/net/wireless/marvell/mwifiex/scan.c:2239 (size 1) elo 16 17:51:58 surfacebook kernel: WARNING: CPU: 0 PID: 498 at drivers/net/wireless/marvell/mwifiex/scan.c:2239 mwifiex_cmd_802_11_scan_ext+0x83/0x90 [mwifiex] | 5.5 |
| 2024-10-21 | CVE-2024-50009 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: cpufreq: amd-pstate: add check for cpufreq_cpu_get's return value cpufreq_cpu_get may return NULL. | 5.5 |
| 2024-10-21 | CVE-2024-50010 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: exec: don't WARN for racy path_noexec check Both i_mode and noexec checks wrapped in WARN_ON stem from an artifact of the previous implementation. | 4.7 |
| 2024-10-21 | CVE-2024-50011 | Infinite Loop vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ASoC: Intel: soc-acpi-intel-rpl-match: add missing empty item There is no links_num in struct snd_soc_acpi_mach {}, and we test !link->num_adr as a condition to end the loop in hda_sdw_machine_select(). So an empty item in struct snd_soc_acpi_link_adr array is required. | 5.5 |
| 2024-10-21 | CVE-2024-50012 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: cpufreq: Avoid a bad reference count on CPU node In the parse_perf_domain function, if the call to of_parse_phandle_with_args returns an error, then the reference to the CPU device node that was acquired at the start of the function would not be properly decremented. Address this by declaring the variable with the __free(device_node) cleanup attribute. | 5.5 |
| 2024-10-21 | CVE-2024-50013 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: exfat: fix memory leak in exfat_load_bitmap() If the first directory entry in the root directory is not a bitmap directory entry, 'bh' will not be released and reassigned, which will cause a memory leak. | 5.5 |
| 2024-10-21 | CVE-2024-50014 | Use of Uninitialized Resource vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: ext4: fix access to uninitialised lock in fc replay path The following kernel trace can be triggered with fstest generic/629 when executed against a filesystem with fast-commit feature enabled: INFO: trying to register non-static key. The code is fine but needs lockdep annotation, or maybe you didn't initialize this object before use? turning off the locking correctness validator.
