https://notcve.org/view.php?id=CVE-2024-50218
In the Linux kernel, the following vulnerability has been resolved: ocfs2: pass u64 to ocfs2_truncate_inline maybe overflow Syzbot reported a kernel BUG in ocfs2_truncate_inline. There are two reasons for this: first, the parameter value passed is greater than ocfs2_max_inline_data_with_xattr, second, the start and end parameters of ocfs2_truncate_inline are "unsigned int". So, we need to add a sanity check for byte_start and byte_len right before ocfs2_truncate_inline() in ocfs2_remove_inode_range(), if they are greater than ocfs2_max_inline_data_with_xattr return -EINVAL. • https://git.kernel.org/stable/c/1afc32b952335f665327a1a9001ba1b44bb76fd9 https://git.kernel.org/stable/c/27d95867bee806cdc448d122bd99f1d8b0544035 https://git.kernel.org/stable/c/95fbed8ae8c32c0977e6be1721c190d8fea23f2f https://git.kernel.org/stable/c/70767689ec6ee5f05fb0a2c17d7ec1927946e486 https://git.kernel.org/stable/c/ecd62f684386fa64f9c0cea92eea361f4e6444c2 https://git.kernel.org/stable/c/2fe5d62e122b040ce7fc4d31aa7fa96ae328cefc https://git.kernel.org/stable/c/88f97a4b5843ce21c1286e082c02a5fb4d8eb473 https://git.kernel.org/stable/c/0b6b8c2055784261de3fb641c5d0d6396 •

https://notcve.org/view.php?id=CVE-2024-50211
In the Linux kernel, the following vulnerability has been resolved: udf: refactor inode_bmap() to handle error Refactor inode_bmap() to handle error since udf_next_aext() can return error now. On situations like ftruncate, udf_extend_file() can now detect errors and bail out early without resorting to checking for particular offsets and assuming internal behavior of these functions. • https://git.kernel.org/stable/c/493447dd8336607fce426f7879e581095f6c606e https://git.kernel.org/stable/c/b22d9a5698abf04341f8fbc30141e0673863c3a6 https://git.kernel.org/stable/c/c226964ec786f3797ed389a16392ce4357697d24 •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-50202 – nilfs2: propagate directory read errors from nilfs_find_entry()
https://notcve.org/view.php?id=CVE-2024-50202
In the Linux kernel, the following vulnerability has been resolved: nilfs2: propagate directory read errors from nilfs_find_entry() Syzbot reported that a task hang occurs in vcs_open() during a fuzzing test for nilfs2. The root cause of this problem is that in nilfs_find_entry(), which searches for directory entries, ignores errors when loading a directory page/folio via nilfs_get_folio() fails. If the filesystem images is corrupted, and the i_size of the directory inode is large, and the directory page/folio is successfully read but fails the sanity check, for example when it is zero-filled, nilfs_check_folio() may continue to spit out error messages in bursts. Fix this issue by propagating the error to the callers when loading a page/folio fails in nilfs_find_entry(). The current interface of nilfs_find_entry() and its callers is outdated and cannot propagate error codes such as -EIO and -ENOMEM returned via nilfs_find_entry(), so fix it together. • https://git.kernel.org/stable/c/2ba466d74ed74f073257f86e61519cb8f8f46184 https://git.kernel.org/stable/c/bb857ae1efd3138c653239ed1e7aef14e1242c81 https://git.kernel.org/stable/c/b4b3dc9e7e604be98a222e9f941f5e93798ca475 https://git.kernel.org/stable/c/c1d0476885d708a932980b0f28cd90d9bd71db39 https://git.kernel.org/stable/c/edf8146057264191d5bfe5b91773f13d936dadd3 https://git.kernel.org/stable/c/270a6f9df35fa2aea01ec23770dc9b3fc9a12989 https://git.kernel.org/stable/c/9698088ac7704e260f492d9c254e29ed7dd8729a https://git.kernel.org/stable/c/efa810b15a25531cbc2f527330947b9fe •

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/ba7f982cdb37ff5a7739dec85d7325ea66fc1496 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/7528c4fb1237512ee18049f852f014eba •
CVSS: -EPSS: 0%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 •
