https://notcve.org/view.php?id=CVE-2024-50201
In the Linux kernel, the following vulnerability has been resolved: drm/radeon: Fix encoder->possible_clones Include the encoder itself in its possible_clones bitmask. In the past nothing validated that drivers were populating possible_clones correctly, but that changed in commit 74d2aacbe840 ("drm: Validate encoder->possible_clones"). Looks like radeon never got the memo and is still not following the rules 100% correctly. This results in some warnings during driver initialization: Bogus possible_clones: [ENCODER:46:TV-46] possible_clones=0x4 (full encoder mask=0x7) WARNING: CPU: 0 PID: 170 at drivers/gpu/drm/drm_mode_config.c:615 drm_mode_config_validate+0x113/0x39c ...

CVSS: -EPSS: %CPEs: 6EXPL: 0CVE-2024-50199 – mm/swapfile: skip HugeTLB pages for unuse_vma
https://notcve.org/view.php?id=CVE-2024-50199
In the Linux kernel, the following vulnerability has been resolved: mm/swapfile: skip HugeTLB pages for unuse_vma I got a bad pud error and lost a 1GB HugeTLB when calling swapoff. The problem can be reproduced by the following steps: 1. Allocate an anonymous 1GB HugeTLB and some other anonymous memory. 2. Swapout the above anonymous memory. 3. run swapoff and we will get a bad pud error in kernel message: mm/pgtable-generic.c:42: bad pud 00000000743d215d(84000001400000e7) We can tell that pud_clear_bad is called by pud_none_or_clear_bad in unuse_pud_range() by ftrace. And therefore the HugeTLB pages will never be freed because we lost it from page table. • https://git.kernel.org/stable/c/0fe6e20b9c4c53b3e97096ee73a0857f60aad43f https://git.kernel.org/stable/c/417d5838ca73c6331ae2fe692fab6c25c00d9a0b https://git.kernel.org/stable/c/e41710f5a61aca9d6baaa8f53908a927dd9e7aa7 https://git.kernel.org/stable/c/6ec0fe3756f941f42f8c57156b8bdf2877b2ebaf https://git.kernel.org/stable/c/bed2b9037806c62166a0ef9a559a1e7e3e1275b8 https://git.kernel.org/stable/c/eb66a833cdd2f7302ee05d05e0fa12a2ca32eb87 https://git.kernel.org/stable/c/7528c4fb1237512ee18049f852f014eba80bbe8d •

https://notcve.org/view.php?id=CVE-2024-50198
In the Linux kernel, the following vulnerability has been resolved: iio: light: veml6030: fix IIO device retrieval from embedded device The dev pointer that is received as an argument in the in_illuminance_period_available_show function references the device embedded in the IIO device, not in the i2c client. dev_to_iio_dev() must be used to accessthe right data. The current implementation leads to a segmentation fault on every attempt to read the attribute because indio_dev gets a NULL assignment. This bug has been present since the first appearance of the driver, apparently since the last version (V6) before getting applied. A constant attribute was used until then, and the last modifications might have not been tested again. • https://git.kernel.org/stable/c/7b779f573c48e1ad6da1d6ea5f181f3ecd666bf6 https://git.kernel.org/stable/c/bf3ab8e1c28f10df0823d4ff312f83c952b06a15 https://git.kernel.org/stable/c/50039aec43a82ad2495f2d0fb0c289c8717b4bb2 https://git.kernel.org/stable/c/bcb90518ccd9e10bf6ab29e31994aab93e4a4361 https://git.kernel.org/stable/c/2cbb41abae65626736b8b52cf3b9339612c5a86a https://git.kernel.org/stable/c/905166531831beb067fffe2bdfc98031ffe89087 https://git.kernel.org/stable/c/c7c44e57750c31de43906d97813273fdffcf7d02 •
CVSS: -EPSS: %CPEs: 5EXPL: 0CVE-2024-50196 – pinctrl: ocelot: fix system hang on level based interrupts
https://notcve.org/view.php?id=CVE-2024-50196
In the Linux kernel, the following vulnerability has been resolved: pinctrl: ocelot: fix system hang on level based interrupts The current implementation only calls chained_irq_enter() and chained_irq_exit() if it detects pending interrupts. ``` for (i = 0; i < info->stride; i++) { uregmap_read(info->map, id_reg + 4 * i, ®); if (!reg) continue; chained_irq_enter(parent_chip, desc); ``` However, in case of GPIO pin configured in level mode and the parent controller configured in edge mode, GPIO interrupt might be lowered by the hardware. In the result, if the interrupt is short enough, the parent interrupt is still pending while the GPIO interrupt is cleared; chained_irq_enter() never gets called and the system hangs trying to service the parent interrupt. Moving chained_irq_enter() and chained_irq_exit() outside the for loop ensures that they are called even when GPIO interrupt is lowered by the hardware. The similar code with chained_irq_enter() / chained_irq_exit() functions wrapping interrupt checking loop may be found in many other drivers: ``` grep -r -A 10 chained_irq_enter drivers/pinctrl ``` • https://git.kernel.org/stable/c/655f5d4662b958122b260be05aa6dfdf8768efe6 https://git.kernel.org/stable/c/4a81800ef05bea5a9896f199677f7b7f5020776a https://git.kernel.org/stable/c/20728e86289ab463b99b7ab4425515bd26aba417 https://git.kernel.org/stable/c/dcbe9954634807ec54e22bde278b5b269f921381 https://git.kernel.org/stable/c/93b8ddc54507a227087c60a0013ed833b6ae7d3c •
CVSS: -EPSS: %CPEs: 6EXPL: 0CVE-2024-50195 – posix-clock: Fix missing timespec64 check in pc_clock_settime()
https://notcve.org/view.php?id=CVE-2024-50195
In the Linux kernel, the following vulnerability has been resolved: posix-clock: Fix missing timespec64 check in pc_clock_settime() As Andrew pointed out, it will make sense that the PTP core checked timespec64 struct's tv_sec and tv_nsec range before calling ptp->info->settime64(). As the man manual of clock_settime() said, if tp.tv_sec is negative or tp.tv_nsec is outside the range [0..999,999,999], it should return EINVAL, which include dynamic clocks which handles PTP clock, and the condition is consistent with timespec64_valid(). As Thomas suggested, timespec64_valid() only check the timespec is valid, but not ensure that the time is in a valid range, so check it ahead using timespec64_valid_strict() in pc_clock_settime() and return -EINVAL if not valid. There are some drivers that use tp->tv_sec and tp->tv_nsec directly to write registers without validity checks and assume that the higher layer has checked it, which is dangerous and will benefit from this, such as hclge_ptp_settime(), igb_ptp_settime_i210(), _rcar_gen4_ptp_settime(), and some drivers can remove the checks of itself. • https://git.kernel.org/stable/c/0606f422b453f76c31ab2b1bd52943ff06a2dcf2 https://git.kernel.org/stable/c/673a1c5a2998acbd429d6286e6cad10f17f4f073 https://git.kernel.org/stable/c/c8789fbe2bbf75845e45302cba6ffa44e1884d01 https://git.kernel.org/stable/c/27abbde44b6e71ee3891de13e1a228aa7ce95bfe https://git.kernel.org/stable/c/a3f169e398215e71361774d13bf91a0101283ac2 https://git.kernel.org/stable/c/1ff7247101af723731ea42ed565d54fb8f341264 https://git.kernel.org/stable/c/d8794ac20a299b647ba9958f6d657051fc51a540 •
