CVSS: -EPSS: 0%CPEs: 7EXPL: 0CVE-2024-50131 – tracing: Consider the NULL character when validating the event length
https://notcve.org/view.php?id=CVE-2024-50131
In the Linux kernel, the following vulnerability has been resolved: tracing: Consider the NULL character when validating the event length strlen() returns a string length excluding the null byte. If the string length equals to the maximum buffer length, the buffer will have no space for the NULL terminating character. This commit checks this condition and returns failure for it. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: rastreo: considerar el carácter NULL al validar la longitud del evento strlen() devuelve una longitud de cadena que excluye el byte nulo. Si la longitud de la cadena es igual a la longitud máxima del búfer, el búfer no tendrá espacio para el carácter de terminación NULL. Esta confirmación verifica esta condición y devuelve un error. • https://git.kernel.org/stable/c/dec65d79fd269d05427c8167090bfc9c3d0b56c4 https://git.kernel.org/stable/c/5e3231b352725ff4a3a0095e6035af674f2d8725 https://git.kernel.org/stable/c/02874ca52df2ca2423ba6122039315ed61c25972 https://git.kernel.org/stable/c/b86b0d6eea204116e4185acc35041ca4ff11a642 https://git.kernel.org/stable/c/f4ed40d1c669bba1a54407d8182acdc405683f29 https://git.kernel.org/stable/c/a14a075a14af8d622c576145455702591bdde09d https://git.kernel.org/stable/c/5fd942598ddeed9a212d1ff41f9f5b47bcc990a7 https://git.kernel.org/stable/c/0b6e2e22cb23105fcb171ab92f0f7516c •
CVSS: -EPSS: 0%CPEs: 7EXPL: 0CVE-2024-50127 – net: sched: fix use-after-free in taprio_change()
https://notcve.org/view.php?id=CVE-2024-50127
In the Linux kernel, the following vulnerability has been resolved: net: sched: fix use-after-free in taprio_change() In 'taprio_change()', 'admin' pointer may become dangling due to sched switch / removal caused by 'advance_sched()', and critical section protected by 'q->current_entry_lock' is too small to prevent from such a scenario (which causes use-after-free detected by KASAN). Fix this by prefer 'rcu_replace_pointer()' over 'rcu_assign_pointer()' to update 'admin' immediately before an attempt to schedule freeing. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: sched: arreglado use-after-free en taprio_change(). En 'taprio_change()', el puntero 'admin' puede quedar colgando debido al cambio/eliminación de sched causado por 'advance_sched()', y la sección crítica protegida por 'q->current_entry_lock' es demasiado pequeña para evitar tal escenario (que causa el use-after-free detectado por KASAN). Solucione esto al preferir 'rcu_replace_pointer()' sobre 'rcu_assign_pointer()' para actualizar 'admin' inmediatamente antes de un intento de liberación de programación. • https://git.kernel.org/stable/c/a3d43c0d56f1b94e74963a2fbadfb70126d92213 https://git.kernel.org/stable/c/2f868ce6013548a713c431c679ef73747a66fcf3 https://git.kernel.org/stable/c/8a283a19026aaae8a773fd8061263cfa315b127f https://git.kernel.org/stable/c/999612996df28d81f163dad530d7f8026e03aec6 https://git.kernel.org/stable/c/fe371f084073e8672a2d7d46b335c3c060d1e301 https://git.kernel.org/stable/c/0d4c0d2844e4eac3aed647f948fd7e60eea56a61 https://git.kernel.org/stable/c/2240f9376f20f8b6463232b4ca7292569217237f https://git.kernel.org/stable/c/f504465970aebb2467da548f7c1efbbf3 •

CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-50116 – nilfs2: fix kernel bug due to missing clearing of buffer delay flag
https://notcve.org/view.php?id=CVE-2024-50116
In the Linux kernel, the following vulnerability has been resolved: nilfs2: fix kernel bug due to missing clearing of buffer delay flag Syzbot reported that after nilfs2 reads a corrupted file system image and degrades to read-only, the BUG_ON check for the buffer delay flag in submit_bh_wbc() may fail, causing a kernel bug. This is because the buffer delay flag is not cleared when clearing the buffer state flags to discard a page/folio or a buffer head. So, fix this. This became necessary when the use of nilfs2's own page clear routine was expanded. This state inconsistency does not occur if the buffer is written normally by log writing. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: nilfs2: se corrige un error del kernel debido a la falta de limpieza del indicador de retraso del búfer Syzbot informó que después de que nilfs2 lee una imagen de sistema de archivos corrupta y se degrada a solo lectura, la comprobación BUG_ON para el indicador de retraso del búfer en submission_bh_wbc() puede fallar, lo que provoca un error del kernel. Esto se debe a que el indicador de retraso del búfer no se borra al borrar los indicadores de estado del búfer para descartar una página/folio o un encabezado de búfer. • https://git.kernel.org/stable/c/8c26c4e2694a163d525976e804d81cd955bbb40c https://git.kernel.org/stable/c/033bc52f35868c2493a2d95c56ece7fc155d7cb3 https://git.kernel.org/stable/c/412a30b1b28d6073ba29c46a2b0f324c5936293f https://git.kernel.org/stable/c/9f2ab98371c2f2488bf3bf3f9b2a73510545e9c1 https://git.kernel.org/stable/c/822203f6355f4b322d21e7115419f6b98284be25 https://git.kernel.org/stable/c/27524f65621f490184f2ace44cd8e5f3685af4a3 https://git.kernel.org/stable/c/743c78d455e784097011ea958b27396001181567 https://git.kernel.org/stable/c/c6f58ff2d4c552927fe9a187774e668eb •
