CVSS: 3.3EPSS: 0%CPEs: 5EXPL: 0CVE-2024-38580 – epoll: be better about file lifetimes
https://notcve.org/view.php?id=CVE-2024-38580
In the Linux kernel, the following vulnerability has been resolved: epoll: be better about file lifetimes epoll can call out to vfs_poll() with a file pointer that may race with the last 'fput()'. That would make f_count go down to zero, and while the ep->mtx locking means that the resulting file pointer tear-down will be blocked until the poll returns, it means that f_count is already dead, and any use of it won't actually get a reference to the file any more: it's dead regardless. Make sure we have a valid ref on the file pointer before we call down to vfs_poll() from the epoll routines. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: epoll: mejore la duración de los archivos epoll puede llamar a vfs_poll() con un puntero de archivo que puede competir con el último 'fput()'. Eso haría que f_count bajara a cero, y aunque el bloqueo ep->mtx significa que el desmontaje del puntero del archivo resultante se bloqueará hasta que regrese la encuesta, significa que f_count ya está muerto y no se podrá utilizar. De hecho, ya no obtengo una referencia al archivo: está muerto de todos modos. • https://git.kernel.org/stable/c/cbfd1088e24ec4c1199756a37cb8e4cd0a4b016e https://git.kernel.org/stable/c/559214eb4e5c3d05e69428af2fae2691ba1eb784 https://git.kernel.org/stable/c/4f65f4defe4e23659275ce5153541cd4f76ce2d2 https://git.kernel.org/stable/c/16e3182f6322575eb7c12e728ad3c7986a189d5d https://git.kernel.org/stable/c/4efaa5acf0a1d2b5947f98abb3acf8bfd966422b https://access.redhat.com/security/cve/CVE-2024-38580 https://bugzilla.redhat.com/show_bug.cgi?id=2293412 •

https://notcve.org/view.php?id=CVE-2024-36969
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix division by zero in setup_dsc_config When slice_height is 0, the division by slice_height in the calculation of the number of slices will cause a division by zero driver crash. This leaves the kernel in a state that requires a reboot. This patch adds a check to avoid the division by zero. The stack trace below is for the 6.8.4 Kernel. I reproduced the issue on a Z16 Gen 2 Lenovo Thinkpad with a Apple Studio Display monitor connected via Thunderbolt. The amdgpu driver crashed with this exception when I rebooted the system with the monitor connected. kernel: ? • https://git.kernel.org/stable/c/a32c8f951c8a456c1c251e1dcdf21787f8066445 https://git.kernel.org/stable/c/91402e0e5de9124a3108db7a14163fcf9a6d322f https://git.kernel.org/stable/c/7e4f50dfc98c49b3dc6875a35c3112522fb25639 https://git.kernel.org/stable/c/f187fcbbb8f8bf10c6687f0beae22509369f7563 https://git.kernel.org/stable/c/308de6be0c9c7ba36915c0d398e771725c0ea911 https://git.kernel.org/stable/c/130afc8a886183a94cf6eab7d24f300014ff87ba • CWE-369: Divide By Zero •

In the Linux kernel, the following vulnerability has been resolved: fs/9p: only translate RWX permissions for plain 9P2000 Garbage in plain 9P2000's perm bits is allowed through, which causes it to be able to set (among others) the suid bit. This was presumably not the intent since the unix extended bits are handled explicitly and conditionally on .u. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: fs/9p: solo traduce permisos RWX para 9P2000 simple. Se permite el paso de basura en bits permanentes de 9P2000 simple, lo que hace que pueda establecer (entre otros) el bit suid. Probablemente esta no era la intención, ya que los bits extendidos de Unix se manejan explícita y condicionalmente en .u. • https://git.kernel.org/stable/c/e90bc596a74bb905e0a45bf346038c3f9d1e868d https://git.kernel.org/stable/c/df1962a199783ecd66734d563caf0fedecf08f96 https://git.kernel.org/stable/c/5a605930e19f451294bd838754f7d66c976a8a2c https://git.kernel.org/stable/c/ad4f65328661392de74e3608bb736fedf3b67e32 https://git.kernel.org/stable/c/ca9b5c81f0c918c63d73d962ed8a8e231f840bc8 https://git.kernel.org/stable/c/e55c601af3b1223a84f9f27f9cdbd2af5e203bf3 https://git.kernel.org/stable/c/157d468e34fdd3cb1ddc07c2be32fb3b02826b02 https://git.kernel.org/stable/c/cd25e15e57e68a6b18dc9323047fe9c68 •
CVSS: 4.4EPSS: 0%CPEs: 5EXPL: 0CVE-2024-36952 – scsi: lpfc: Move NPIV's transport unregistration to after resource clean up
https://notcve.org/view.php?id=CVE-2024-36952
In the Linux kernel, the following vulnerability has been resolved: scsi: lpfc: Move NPIV's transport unregistration to after resource clean up There are cases after NPIV deletion where the fabric switch still believes the NPIV is logged into the fabric. This occurs when a vport is unregistered before the Remove All DA_ID CT and LOGO ELS are sent to the fabric. Currently fc_remove_host(), which calls dev_loss_tmo for all D_IDs including the fabric D_ID, removes the last ndlp reference and frees the ndlp rport object. This sometimes causes the race condition where the final DA_ID and LOGO are skipped from being sent to the fabric switch. Fix by moving the fc_remove_host() and scsi_remove_host() calls after DA_ID and LOGO are sent. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: scsi: lpfc: Mover la anulación del registro de transporte de NPIV a después de la limpieza de recursos. Hay casos después de la eliminación de NPIV en los que el conmutador de tejido todavía cree que el NPIV está registrado en el tejido. • https://git.kernel.org/stable/c/f2c7f029051edc4b394bb48edbe2297575abefe0 https://git.kernel.org/stable/c/0936809d968ecf81e0726fbd02ff2a5732d960c3 https://git.kernel.org/stable/c/76337eb8daee32bcc67742efab3168ed4ca299d0 https://git.kernel.org/stable/c/718602cd15f4c5710850090ea3066a89eeb46278 https://git.kernel.org/stable/c/4ddf01f2f1504fa08b766e8cfeec558e9f8eef6c https://access.redhat.com/security/cve/CVE-2024-36952 https://bugzilla.redhat.com/show_bug.cgi?id=2284598 • CWE-459: Incomplete Cleanup •
