CVSS: 5.5EPSS: 0%CPEs: 5EXPL: 0CVE-2024-27393 – xen-netfront: Add missing skb_mark_for_recycle
https://notcve.org/view.php?id=CVE-2024-27393
In the Linux kernel, the following vulnerability has been resolved: xen-netfront: Add missing skb_mark_for_recycle Notice that skb_mark_for_recycle() is introduced later than fixes tag in commit 6a5bcd84e886 ("page_pool: Allow drivers to hint on SKB recycling"). It is believed that fixes tag were missing a call to page_pool_release_page() between v5.9 to v5.14, after which is should have used skb_mark_for_recycle(). Since v6.6 the call page_pool_release_page() were removed (in commit 535b9c61bdef ("net: page_pool: hide page_pool_release_page()") and remaining callers converted (in commit 6bfef2ec0172 ("Merge branch 'net-page_pool-remove-page_pool_release_page'")). This leak became visible in v6.8 via commit dba1b8a7ab68 ("mm/page_pool: catch page_pool memory leaks"). En el kernel de Linux, se resolvió la siguiente vulnerabilidad: xen-netfront: agrega skb_mark_for_recycle faltante. Tenga en cuenta que skb_mark_for_recycle() se introduce más tarde que la etiqueta de corrección en el commit 6a5bcd84e886 ("page_pool: permitir que los controladores indiquen el reciclaje de SKB"). Se cree que a la etiqueta de correcciones le faltaba una llamada a page_pool_release_page() entre v5.9 y v5.14, después de lo cual debería haber usado skb_mark_for_recycle(). Desde v6.6, la llamada page_pool_release_page() se eliminó (en el commit 535b9c61bdef ("net: page_pool: hide page_pool_release_page()") y las personas que llaman restantes se convirtieron (en el commit 6bfef2ec0172 ("Merge Branch 'net-page_pool-remove-page_pool_release_page'") ). • https://git.kernel.org/stable/c/6c5aa6fc4defc2a0977a2c59e4710d50fa1e834c https://git.kernel.org/stable/c/4143b9479caa29bb2380f3620dcbe16ea84eb3b1 https://git.kernel.org/stable/c/7c1250796b6c262b505a46192f4716b8c6a6a8c6 https://git.kernel.org/stable/c/27aa3e4b3088426b7e34584274ad45b5afaf7629 https://git.kernel.org/stable/c/c8b7b2f158d9d4fb89cd2f68244af154f7549bb4 https://git.kernel.org/stable/c/037965402a010898d34f4e35327d22c0a95cd51f http://www.openwall.com/lists/oss-security/2024/05/08/4 http://xenbits.xen.org/xsa/advisory-457.html https:& •
CVSS: -EPSS: 0%CPEs: 8EXPL: 1CVE-2023-52654 – io_uring/af_unix: disable sending io_uring over sockets
https://notcve.org/view.php?id=CVE-2023-52654
In the Linux kernel, the following vulnerability has been resolved: io_uring/af_unix: disable sending io_uring over sockets File reference cycles have caused lots of problems for io_uring in the past, and it still doesn't work exactly right and races with unix_stream_read_generic(). The safest fix would be to completely disallow sending io_uring files via sockets via SCM_RIGHT, so there are no possible cycles invloving registered files and thus rendering SCM accounting on the io_uring side unnecessary. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: io_uring/af_unix: deshabilita el envío de io_uring a través de sockets Los ciclos de referencia de archivos han causado muchos problemas para io_uring en el pasado, y todavía no funciona exactamente correctamente y corre con unix_stream_read_generic(). La solución más segura sería no permitir por completo el envío de archivos io_uring a través de sockets a través de SCM_RIGHT, de modo que no haya ciclos posibles que involucren archivos registrados y, por lo tanto, hagan innecesaria la contabilidad SCM en el lado io_uring. • https://github.com/FoxyProxys/CVE-2023-52654 https://git.kernel.org/stable/c/04df9719df1865f6770af9bc7880874af0e594b2 https://git.kernel.org/stable/c/c378c479c5175833bb22ff71974cda47d7b05401 https://git.kernel.org/stable/c/813d8fe5d30388f73a21d3a2bf46b0a1fd72498c https://git.kernel.org/stable/c/0091bfc81741b8d3aeb3b7ab8636f911b2de6e80 https://git.kernel.org/stable/c/b4293c01ee0d0ecdd3cb5801e13f62271144667a https://git.kernel.org/stable/c/75e94c7e8859e58aadc15a98cc9704edff47d4f2 https://git.kernel.org/stable/c/18824f592aad4124d79751bbc1500ea86ac3ff29 https:/& •

In the Linux kernel, the following vulnerability has been resolved: drm/radeon: add a force flush to delay work when radeon Although radeon card fence and wait for gpu to finish processing current batch rings, there is still a corner case that radeon lockup work queue may not be fully flushed, and meanwhile the radeon_suspend_kms() function has called pci_set_power_state() to put device in D3hot state.

In the Linux kernel, the following vulnerability has been resolved: thermal/int340x_thermal: handle data_vault when the value is ZERO_SIZE_PTR In some case, the GDDV returns a package with a buffer which has zero length. It causes that kmemdup() returns ZERO_SIZE_PTR (0x10). Then the data_vault_read() got NULL point dereference problem when accessing the 0x10 value in data_vault. [ 71.024560] BUG: kernel NULL pointer dereference, address: 0000000000000010 This patch uses ZERO_OR_NULL_PTR() for checking ZERO_SIZE_PTR or NULL value in data_vault. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: Thermal/int340x_thermal: maneja data_vault cuando el valor es ZERO_SIZE_PTR. En algunos casos, el GDDV devuelve un paquete con un buffer que tiene longitud cero.
