CVSS: -EPSS: 0%CPEs: 5EXPL: 0CVE-2024-50191 – ext4: don't set SB_RDONLY after filesystem errors
https://notcve.org/view.php?id=CVE-2024-50191
In the Linux kernel, the following vulnerability has been resolved: ext4: don't set SB_RDONLY after filesystem errors When the filesystem is mounted with errors=remount-ro, we were setting SB_RDONLY flag to stop all filesystem modifications. We knew this misses proper locking (sb->s_umount) and does not go through proper filesystem remount procedure but it has been the way this worked since early ext2 days and it was good enough for catastrophic situation damage mitigation. Recently, syzbot has found a way (see link) to trigger warnings in filesystem freezing because the code got confused by SB_RDONLY changing under its hands. Since these days we set EXT4_FLAGS_SHUTDOWN on the superblock which is enough to stop all filesystem modifications, modifying SB_RDONLY shouldn't be needed. So stop doing that. • https://git.kernel.org/stable/c/fbb177bc1d6487cd3e9b50ae0be2781b7297980d https://git.kernel.org/stable/c/4061e07f040a091f694f461b86a26cf95ae66439 https://git.kernel.org/stable/c/58c0648e4c773f5b54f0cb63bc8c7c6bf52719a9 https://git.kernel.org/stable/c/ee77c388469116565e009eaa704a60bc78489e09 https://git.kernel.org/stable/c/d3476f3dad4ad68ae5f6b008ea6591d1520da5d8 •

https://notcve.org/view.php?id=CVE-2024-50188
In the Linux kernel, the following vulnerability has been resolved: net: phy: dp83869: fix memory corruption when enabling fiber When configuring the fiber port, the DP83869 PHY driver incorrectly calls linkmode_set_bit() with a bit mask (1 << 10) rather than a bit number (10). This corrupts some other memory location -- in case of arm64 the priv pointer in the same structure. Since the advertising flags are updated from supported at the end of the function the incorrect line isn't needed at all and can be removed. • https://git.kernel.org/stable/c/a29de52ba2a156873505d8b8cef44e69925b8114 https://git.kernel.org/stable/c/21b5af7f0c99b3bf1fd02016e6708b613acbcaf4 https://git.kernel.org/stable/c/ad0d76b8ee5db063791cc2e7a30ffc9852ac37c4 https://git.kernel.org/stable/c/c1944b4253649fc6f2fb53e7d6302eb414d2182c https://git.kernel.org/stable/c/9ca634676ff66e1d616259e136f96f96b2a1759a https://git.kernel.org/stable/c/e3f2de32dae35bc7d173377dc97b5bc9fcd9fc84 https://git.kernel.org/stable/c/a842e443ca8184f2dc82ab307b43a8b38defd6a5 •
CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2024-50187 – drm/vc4: Stop the active perfmon before being destroyed
https://notcve.org/view.php?id=CVE-2024-50187
In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Stop the active perfmon before being destroyed Upon closing the file descriptor, the active performance monitor is not stopped. Although all perfmons are destroyed in `vc4_perfmon_close_file()`, the active performance monitor's pointer (`vc4->active_perfmon`) is still retained. If we open a new file descriptor and submit a few jobs with performance monitors, the driver will attempt to stop the active performance monitor using the stale pointer in `vc4->active_perfmon`. However, this pointer is no longer valid because the previous process has already terminated, and all performance monitors associated with it have been destroyed and freed. To fix this, when the active performance monitor belongs to a given process, explicitly stop it before destroying and freeing it. • https://git.kernel.org/stable/c/65101d8c9108201118efa7e08f4e2c57f438deb9 https://git.kernel.org/stable/c/75452da51e2403e14be007df80d133e1443fc967 https://git.kernel.org/stable/c/937943c042503dc6087438bf3557f9057a588ba0 https://git.kernel.org/stable/c/c9adba739d5f7cdc47a7754df4a17b47b1ecf513 https://git.kernel.org/stable/c/0b2ad4f6f2bec74a5287d96cb2325a5e11706f22 •

In the Linux kernel, the following vulnerability has been resolved: virtio_pmem: Check device status before requesting flush If a pmem device is in a bad status, the driver side could wait for host ack forever in virtio_pmem_flush(), causing the system to hang.
