https://notcve.org/view.php?id=CVE-2024-50092
In the Linux kernel, the following vulnerability has been resolved: net: netconsole: fix wrong warning A warning is triggered when there is insufficient space in the buffer for userdata. However, this is not an issue since userdata will be sent in the next iteration. Current warning message: ------------[ cut here ]------------ WARNING: CPU: 13 PID: 3013042 at drivers/net/netconsole.c:1122 write_ext_msg+0x3b6/0x3d0 ? write_ext_msg+0x3b6/0x3d0 console_flush_all+0x1e9/0x330 The code incorrectly issues a warning when this_chunk is zero, which is a valid scenario. The warning should only be triggered when this_chunk is negative. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: netconsole: fix wrong Warning Se activa una advertencia cuando no hay suficiente espacio en el búfer para los datos del usuario. • https://git.kernel.org/stable/c/1ec9daf950936c2a1c591596e83c09ce2eb12ade https://git.kernel.org/stable/c/712a3af3710263444217df54e7f337f99df198d2 https://git.kernel.org/stable/c/d94785bb46b6167382b1de3290eccc91fa98df53 •

In the Linux kernel, the following vulnerability has been resolved: dm vdo: don't refer to dedupe_context after releasing it Clear the dedupe_context pointer in a data_vio whenever ownership of the context is lost, so that vdo can't examine it accidentally. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: dm vdo: no hacer referencia a dedupe_context después de liberarlo. Borre el puntero dedupe_context en un data_vio siempre que se pierda la propiedad del contexto, de modo que vdo no pueda examinarlo accidentalmente. • https://git.kernel.org/stable/c/63ef073084c67878d7a92e15ad055172da3f05a3 https://git.kernel.org/stable/c/0808ebf2f80b962e75741a41ced372a7116f1e26 •

https://notcve.org/view.php?id=CVE-2024-50090
In the Linux kernel, the following vulnerability has been resolved: drm/xe/oa: Fix overflow in oa batch buffer By default xe_bb_create_job() appends a MI_BATCH_BUFFER_END to batch buffer, this is not a problem if batch buffer is only used once but oa reuses the batch buffer for the same metric and at each call it appends a MI_BATCH_BUFFER_END, printing the warning below and then overflowing.

In the Linux kernel, the following vulnerability has been resolved: unicode: Don't special case ignorable code points We don't need to handle them separately. Instead, just let them decompose/casefold to themselves. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: unicode: No aplicar mayúsculas y minúsculas especiales a los puntos de código que se puedan ignorar. No necesitamos manejarlos por separado. En su lugar, simplemente dejamos que se descompongan o se conviertan en mayúsculas y minúsculas por sí mismos. • https://git.kernel.org/stable/c/18b5f47e7da46d3a0d7331e48befcaf151ed2ddf https://git.kernel.org/stable/c/39fffca572844d733b137a0ff9eacd67b9b0c8e3 https://git.kernel.org/stable/c/651b954cd8d5b0a358ceb47c93876bb6201224e4 https://git.kernel.org/stable/c/21526498d25e54bda3c650f756493d63fd9131b7 https://git.kernel.org/stable/c/ac20736861f3c9c8e0a78273a4c57e9bcb0d8cc6 https://git.kernel.org/stable/c/876d3577a5b353e482d9228d45fa0d82bf1af53a https://git.kernel.org/stable/c/5c26d2f1d3f5e4be3e196526bead29ecb139cf91 •

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix uninitialized pointer free in add_inode_ref() The add_inode_ref() function does not initialize the "name" struct when it is declared. If any of the following calls to "read_one_inode() returns NULL, dir = read_one_inode(root, parent_objectid); if (!dir) { ret = -ENOENT; goto out; } inode = read_one_inode(root, inode_objectid); if (!inode) { ret = -EIO; goto out; } then "name.name" would be freed on "out" before being initialized. out: ... kfree(name.name); This issue was reported by Coverity with CID 1526744. • https://git.kernel.org/stable/c/1cf474cd474bc5d3ef63086ffd009a87a5b7bb2e https://git.kernel.org/stable/c/e43eec81c5167b655b72c781b0e75e62a05e415e https://git.kernel.org/stable/c/12cf028381aa19bc38465341512c280256e8d82d https://git.kernel.org/stable/c/e11ce03b58743bf1e096c48fcaa7e6f08eb75dfa https://git.kernel.org/stable/c/a941f3d5b1469c60a7e70e775584f110b47e0d16 https://git.kernel.org/stable/c/66691c6e2f18d2aa4b22ffb624b9bdc97e9979e4 •
