Descriptions

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'") ). Esta fuga se hizo visible en la versión 6.8 mediante el commit dba1b8a7ab68 ("mm/page_pool: captura pérdidas de memoria en page_pool").

Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition, leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a denial of service.
