https://notcve.org/view.php?id=CVE-2024-27067
In the Linux kernel, the following vulnerability has been resolved: xen/evtchn: avoid WARN() when unbinding an event channel When unbinding a user event channel, the related handler might be called a last time in case the kernel was built with CONFIG_DEBUG_SHIRQ. This might cause a WARN() in the handler. Avoid that by adding an "unbinding" flag to struct user_event which will short circuit the handler. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: xen/evtchn: evite WARN() al desvincular un canal de eventos Al desvincular un canal de eventos de usuario, es posible que se llame al controlador relacionado por última vez en caso de que el kernel se haya compilado con CONFIG_DEBUG_SHIRQ. Esto podría provocar un WARN() en el controlador. Evite esto agregando un indicador de "desvinculación" a la estructura user_event que provocará un cortocircuito en el controlador. • https://git.kernel.org/stable/c/3c8f5965a99397368d3762a9814a21a3e442e1a4 https://git.kernel.org/stable/c/9e90e58c11b74c2bddac4b2702cf79d36b981278 https://git.kernel.org/stable/c/99e425032c6ec13584d3cd33846e0c7307501b47 https://git.kernel.org/stable/c/35485dad6e28f9b17884764d4692b1655cb848d0 https://git.kernel.org/stable/c/9e2d4b58c1da48a32905802aaeadba7084b46895 https://git.kernel.org/stable/c/51c23bd691c0f1fb95b29731c356c6fd69925d17 •
CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2024-27066 – virtio: packed: fix unmap leak for indirect desc table
https://notcve.org/view.php?id=CVE-2024-27066
In the Linux kernel, the following vulnerability has been resolved: virtio: packed: fix unmap leak for indirect desc table When use_dma_api and premapped are true, then the do_unmap is false. Because the do_unmap is false, vring_unmap_extra_packed is not called by detach_buf_packed. if (unlikely(vq->do_unmap)) { curr = id; for (i = 0; i < state->num; i++) { vring_unmap_extra_packed(vq, &vq->packed.desc_extra[curr]); curr = vq->packed.desc_extra[curr].next; } } So the indirect desc table is not unmapped. This causes the unmap leak. So here, we check vq->use_dma_api instead. Synchronously, dma info is updated based on use_dma_api judgment This bug does not occur, because no driver use the premapped with indirect. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: virtio: empaquetado: corrige la fuga de desasignación para la tabla desc indirecta Cuando use_dma_api y premapped son verdaderos, entonces do_unmap es falso. Debido a que do_unmap es falso, detach_buf_packed no llama a vring_unmap_extra_packed. if (improbable(vq->do_unmap)) { curr = id; for (i = 0; i < estado->num; i++) { vring_unmap_extra_packed(vq, &vq->packed.desc_extra[curr]); curr = vq->packed.desc_extra[curr].next; } } Por lo tanto, la tabla de descripción indirecta no está desasignada. • https://git.kernel.org/stable/c/b319940f83c21bb4c1fabffe68a862be879a6193 https://git.kernel.org/stable/c/e142169aca5546ae6619c39a575cda8105362100 https://git.kernel.org/stable/c/75450ff8c6fe8755bf5b139b238eaf9739cfd64e https://git.kernel.org/stable/c/51bacd9d29bf98c3ebc65e4a0477bb86306b4140 https://git.kernel.org/stable/c/d5c0ed17fea60cca9bc3bf1278b49ba79242bbcd •

In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: Fix a memory leak in nf_tables_updchain If nft_netdev_register_hooks() fails, the memory associated with nft_stats is not freed, causing a memory leak.

In the Linux kernel, the following vulnerability has been resolved: SUNRPC: fix a memleak in gss_import_v2_context The ctx->mech_used.data allocated by kmemdup is not freed in neither gss_import_v2_context nor it only caller gss_krb5_import_sec_context, which frees ctx on error. Thus, this patch reform the last call of gss_import_v2_context to the gss_krb5_import_ctx_v2, preventing the memleak while keepping the return formation. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: SUNRPC: corrige una fuga de memport en gss_import_v2_context El ctx->mech_used.data asignado por kmemdup no se libera ni en gss_import_v2_context ni solo en el llamador gss_krb5_import_sec_context, lo que libera a ctx en caso de error.
