CVE-2025-38221

CVE-2025-38221 relates to a Linux kernel ext4 punching hole offset vulnerability. The available connected documents describe a fix for out-of-bounds punching: punching a hole with a start offset that exceeds max_end could yield a negative length in truncate_inode_partial_folio during page cache t...

CVE-2025-38221

In the Linux kernel, the following vulnerability has been resolved: ext4: fix out of bounds punch offset Punching a hole with a start offset that exceeds maxend is not permitted and will result in a negative length in the truncateinodepartialfolio function while truncating the page cache,...

CVE-2025-38220 ext4: only dirty folios when data journaling regular files

In the Linux kernel, the following vulnerability has been resolved: ext4: only dirty folios when data journaling regular files fstest generic/388 occasionally reproduces a crash that looks as follows: BUG: kernel NULL pointer dereference, address: 0000000000000000 ... Call Trace:...

CVE-2025-38220

CVE-2025-38220 affects the Linux kernel ext4 subsystem. The vulnerability occurs when processing an orphan-list symlink inode during truncation; partial block zeroing calls ext4_dirty_journalled_data() which invokes folio_mark_dirty() via mapping->a_ops->dirty_folio(), but symlink inodes la...

CVE-2025-38219

CVE-2025-38219 affects the Linux kernel F2FS code path. The issue is a downgrade-related negative i_nlink scenario that could trigger a kernel warning; the vulnerability was resolved in the cited upstream code path (f2fs_i_links_write -> f2fs_drop_nlink -> f2fs_unlink), as shown in the conn...

CVE-2025-38218

CVE-2025-38218 affects the Linux kernel with f2fs: a sanity check failure in sit_bitmap_size can lead to a kernel panic during resize/mount. The issue arises when sit_i->bitmap_size is 192, making sit bitmap size 1536, but with MAIN_SEGS at 261893 the sit_blk_cnt becomes 4762; build_sit_entrie...

CVE-2025-38217

In the Linux kernel, the following vulnerability has been resolved: hwmon: ftsteutates Fix TOCTOU race in ftsread In the ftsread function, when handling hwmonpwmautochannelstemp, the code accesses the shared variable data-fansourcechannel twice without holding any locks. It is first checked again...

CVE-2025-38215

In CVE-2025-38215, the Linux kernel fbdev subsystem had a null-ptr-deref risk in fb_videomode_to_var when do_register_framebuffer allocated fb_videomode memory unsuccessfully. The fix prevents registering fb_info unless its mode is set and moves fb_add_videomode() earlier in do_register_framebuff...

CVE-2025-38216

CVE-2025-38216 (Linux kernel) affects iommu/vt-d context entry setup order for aliased PCI devices behind PCIe-to-PCI bridges. The issue arose after commit 2031c469f816 changed domain attach context entry setup from set-and-check to clear-and-reset, regressing PCI aliased devices and causing inpu...

CVE-2025-38215 fbdev: Fix do_register_framebuffer to prevent null-ptr-deref in fb_videomode_to_var

In the Linux kernel, the following vulnerability has been resolved: fbdev: Fix doregisterframebuffer to prevent null-ptr-deref in fbvideomodetovar If fbaddvideomode in doregisterframebuffer fails to allocate memory for fbvideomode, it will later lead to a null-ptr dereference in fbvideomodetovar,...

CVE-2025-38214 fbdev: Fix fb_set_var to prevent null-ptr-deref in fb_videomode_to_var

In the Linux kernel, the following vulnerability has been resolved: fbdev: Fix fbsetvar to prevent null-ptr-deref in fbvideomodetovar If fbaddvideomode in fbsetvar fails to allocate memory for fbvideomode, later it may lead to a null-ptr dereference in fbvideomodetovar, as the fbinfo is registere...
