CVE-2026-31519

CVE-2026-31519 affects the Linux kernel btrfs subsystem. A race during subvolume creation and orphan cleanup can leave a valid subvolume’s dentry in a broken state, marked as a broken entry in the directory cache, preventing deletion or new writes in that location. Root cause: btrfs_orphan_cleanu...

CVE-2026-31489 spi: meson-spicc: Fix double-put in remove path

In the Linux kernel, the following vulnerability has been resolved: spi: meson-spicc: Fix double-put in remove path mesonspiccprobe registers the controller with devmspiregistercontroller, so teardown already drops the controller reference via devm cleanup. Calling spicontrollerput again in...

CVE-2026-31489

This CVE (CVE-2026-31489) affects the Linux kernel meson-spicc SPI controller driver. The vulnerability arises from a double-put: meson_spicc_probe() registers the controller with devm_spi_register_controller(), and the removal path erroneously calls spi_controller_put() again in meson_spicc_remo...

CVE-2026-31475 ASoC: sma1307: fix double free of devm_kzalloc() memory

In the Linux kernel, the following vulnerability has been resolved: ASoC: sma1307: fix double free of devmkzalloc memory A previous change added NULL checks and cleanup for allocation failures in sma1307settingloaded. However, the cleanup for modeset entries is wrong. Those entries are allocated...

CVE-2026-31475

In CVE-2026-31475, the Linux kernel ASoC sma1307 component had a double-free issue: mode_set entries allocated with devm_kzalloc() were (incorrectly) freed with kfree() in an error path. The remedy documented across multiple sources is to drop the manual kfree() loop and rely on device resource m...

In the Linux kernel, the following vulnerability has been resolved: media: mc, v4l2: serialize REINIT and REQBUFS with reqqueuemutex MEDIAREQUESTIOCREINIT can run concurrently with VIDIOCREQBUFS0 queue teardown paths. This can race request object cleanup against vb2 queue cancellation and lead to...

CVE-2026-31471

In CVE-2026-31471, the Linux kernel’s xfrm: iptfs path had a use-after-free-like issue during IPTFS clone state setup. iptfs_clone_state() stored x->mode_data before allocating the reorder window; if allocation failed, the code freed the cloned state but left x->mode_data pointing at freed ...
