CVE-2026-64075

The CVE describes a Linux kernel issue in fprobe: after registering fprobe to an rcu-hlist via a function-graph tracer rewrite, unregister_fprobe() did not wait for the RCU grace period, risking use-after-free when the fprobe is released soon after unregistering in fprobe events and sample code. ...

CVE-2026-64063

CVE-2026-64063 concerns the Linux kernel netfs subsystem, where streaming writes could partially overwrite dirty folios without correctly updating state. The issue occurred when a partially written streaming page was overwritten by a subsequent write: netfs_perform_write() could copy over the pag...

CVE-2026-64063 netfs: Fix streaming write being overwritten

In the Linux kernel, the following vulnerability has been resolved: netfs: Fix streaming write being overwritten In order to avoid reading whilst writing, netfslib will allow "streaming writes" in which dirty data is stored directly into folios without reading them first. Such folios are marked...

In the Linux kernel, the following vulnerability has been resolved: ASoC: codecs: fs210x: fix possible buffer overflow In fs210xeffectsceneinfo, a string was copied like this: strscpyDST, SRC, strlenSRC + 1; A buffer overflow would happen if strlenSRC = sizeofDST. Actually, strscpy must be used...

CVE-2026-64041

The issue CVE-2026-64041 affects the Linux kernel ASoC fs210x codec driver. In fs210x_effect_scene_info(), a string is copied with strscpy using strlen(SRC) + 1 (DST) instead of a bound-limited size, enabling a potential buffer overflow when strlen(SRC) >= sizeof(DST). The fix uses correct bou...
