In the Linux kernel, the following vulnerability has been resolved: wifi: wilc1000: use vmm_table as array in wilc struct Enabling KASAN and running some iperf tests raises some memory issues with vmm_table: BUG: KASAN: slab-out-of-bounds in wilc_wlan_handle_txq+0x6ac/0xdb4 Write of size 4 at addr c3a61540 by task wlan0-tx/95 KASAN detects that we are writing data beyond range allocated to vmm_table. There is indeed a mismatch between the size passed to allocator in wilc_wlan_init, and the range of possible indexes used later: allocation size is missing a multiplication by sizeof(u32) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: wifi: wilc1000: use vmm_table como matriz en wilc struct. Al habilitar KASAN y ejecutar algunas pruebas de iperf se generan algunos problemas de memoria con vmm_table: BUG: KASAN: slab-out-of-bounds en wilc_wlan_handle_txq +0x6ac/0xdb4 Escritura de tamaño 4 en la dirección c3a61540 mediante la tarea wlan0-tx/95 KASAN detecta que estamos escribiendo datos más allá del rango asignado a vmm_table. De hecho, existe una discrepancia entre el tamaño pasado al asignador en wilc_wlan_init y el rango de posibles índices utilizados más adelante: al tamaño de la asignación le falta una multiplicación por sizeof(u32) • https://git.kernel.org/stable/c/32dd0b22a5ba1dd296ccf2caf46ad44c3a8d5d98 https://git.kernel.org/stable/c/40b717bfcefab28a0656b8caa5e43d5449e5a671 https://git.kernel.org/stable/c/5212d958f6518003cd98c9886f8e8aedcfc25741 https://git.kernel.org/stable/c/541b3757fd443a68ed8d25968eae511a8275e7c8 https://git.kernel.org/stable/c/4b0d6ddb6466d10df878a7787f175a0e4adc3e27 https://git.kernel.org/stable/c/6aaf7cd8bdfe245d3c9a8b48fe70c2011965948e https://git.kernel.org/stable/c/3ce1c2c3999b232258f7aabab311d47dda75605c https://git.kernel.org/stable/c/05ac1a198a63ad66bf5ae8b7321407c10 •
CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2023-52767 – tls: fix NULL deref on tls_sw_splice_eof() with empty record
https://notcve.org/view.php?id=CVE-2023-52767
In the Linux kernel, the following vulnerability has been resolved: tls: fix NULL deref on tls_sw_splice_eof() with empty record syzkaller discovered that if tls_sw_splice_eof() is executed as part of sendfile() when the plaintext/ciphertext sk_msg are empty, the send path gets confused because the empty ciphertext buffer does not have enough space for the encryption overhead. This causes tls_push_record() to go on the `split = true` path (which is only supposed to be used when interacting with an attached BPF program), and then get further confused and hit the tls_merge_open_record() path, which then assumes that there must be at least one populated buffer element, leading to a NULL deref. It is possible to have empty plaintext/ciphertext buffers if we previously bailed from tls_sw_sendmsg_locked() via the tls_trim_both_msgs() path. tls_sw_push_pending_record() already handles this case correctly; let's do the same check in tls_sw_splice_eof(). En el kernel de Linux, se resolvió la siguiente vulnerabilidad: tls: corrige NULL deref en tls_sw_splice_eof() con registro vacío syzkaller descubrió que si tls_sw_splice_eof() se ejecuta como parte de sendfile() cuando el texto plano/texto cifrado sk_msg está vacío, el envío La ruta se confunde porque el búfer de texto cifrado vacío no tiene suficiente espacio para la sobrecarga de cifrado. Esto hace que tls_push_record() vaya a la ruta `split = true` (que se supone que solo debe usarse al interactuar con un programa BPF adjunto), y luego se confunda aún más y acceda a la ruta tls_merge_open_record(), que luego supone que hay debe haber al menos un elemento de búfer poblado, lo que lleva a una deref NULL. Es posible tener buffers de texto plano/texto cifrado vacíos si previamente salimos de tls_sw_sendmsg_locked() a través de la ruta tls_trim_both_msgs(). tls_sw_push_pending_record() ya maneja este caso correctamente; hagamos la misma verificación en tls_sw_splice_eof(). • https://git.kernel.org/stable/c/df720d288dbb1793e82b6ccbfc670ec871e9def4 https://git.kernel.org/stable/c/2214e2bb5489145aba944874d0ee1652a0a63dc8 https://git.kernel.org/stable/c/53f2cb491b500897a619ff6abd72f565933760f0 https://git.kernel.org/stable/c/944900fe2736c07288efe2d9394db4d3ca23f2c9 •

https://notcve.org/view.php?id=CVE-2023-52765
In the Linux kernel, the following vulnerability has been resolved: mfd: qcom-spmi-pmic: Fix revid implementation The Qualcomm SPMI PMIC revid implementation is broken in multiple ways. First, it assumes that just because the sibling base device has been registered that means that it is also bound to a driver, which may not be the case (e.g. due to probe deferral or asynchronous probe). This could trigger a NULL-pointer dereference when attempting to access the driver data of the unbound device. Second, it accesses driver data of a sibling device directly and without any locking, which means that the driver data may be freed while it is being accessed (e.g. on driver unbind). Third, it leaks a struct device reference to the sibling device which is looked up using the spmi_device_from_of() every time a function (child) device is calling the revid function (e.g. on probe). Fix this mess by reimplementing the revid lookup so that it is done only at probe of the PMIC device; the base device fetches the revid info from the hardware, while any secondary SPMI device fetches the information from the base device and caches it so that it can be accessed safely from its children. If the base device has not been probed yet then probe of a secondary device is deferred. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: mfd: qcom-spmi-pmic: reparación de la implementación revid. La implementación revid de Qualcomm SPMI PMIC está rota de varias maneras. • https://git.kernel.org/stable/c/e9c11c6e3a0e93903f5a13f8d2f97ae1bba512e1 https://git.kernel.org/stable/c/db98de0809f12b0edb9cd1be78e1ec1bfeba8f40 https://git.kernel.org/stable/c/4ce77b023d42a9f1062eecf438df1af4b4072eb2 https://git.kernel.org/stable/c/affae18838db5e6b463ee30c821385695af56dc2 https://git.kernel.org/stable/c/7b439aaa62fee474a0d84d67a25f4984467e7b95 • CWE-476: NULL Pointer Dereference •
