https://notcve.org/view.php?id=CVE-2024-35988
In the Linux kernel, the following vulnerability has been resolved: riscv: Fix TASK_SIZE on 64-bit NOMMU On NOMMU, userspace memory can come from anywhere in physical RAM. The current definition of TASK_SIZE is wrong if any RAM exists above 4G, causing spurious failures in the userspace access routines. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: riscv: corrige TASK_SIZE en NOMMU de 64 bits En NOMMU, la memoria del espacio de usuario puede provenir de cualquier lugar de la RAM física. La definición actual de TASK_SIZE es incorrecta si existe RAM por encima de 4G, lo que provoca fallos falsos en las rutinas de acceso al espacio de usuario. • https://git.kernel.org/stable/c/6bd33e1ece528f67646db33bf97406b747dafda0 https://git.kernel.org/stable/c/04bf2e5f95c1a52e28a7567a507f926efe31c3b6 https://git.kernel.org/stable/c/52e8a42b11078d2aad4b9ba96503d77c7299168b https://git.kernel.org/stable/c/4201b8c8f2c32af321fb50867e68ac6c1cbed4be https://git.kernel.org/stable/c/a0f0dbbb1bc49fa0de18e92c36492ff6d804cdaa https://git.kernel.org/stable/c/efdcfa554b6eb228943ef1dd4d023c606be647d2 https://git.kernel.org/stable/c/6065e736f82c817c9a597a31ee67f0ce4628e948 https://lists.debian.org/debian-lts-announce/2024/06/ •
CVSS: 5.5EPSS: 0%CPEs: 4EXPL: 0CVE-2024-35986 – phy: ti: tusb1210: Resolve charger-det crash if charger psy is unregistered
https://notcve.org/view.php?id=CVE-2024-35986
In the Linux kernel, the following vulnerability has been resolved: phy: ti: tusb1210: Resolve charger-det crash if charger psy is unregistered The power_supply frame-work is not really designed for there to be long living in kernel references to power_supply devices. Specifically unregistering a power_supply while some other code has a reference to it triggers a WARN in power_supply_unregister(): WARN_ON(atomic_dec_return(&psy->use_cnt)); Folllowed by the power_supply still getting removed and the backing data freed anyway, leaving the tusb1210 charger-detect code with a dangling reference, resulting in a crash the next time tusb1210_get_online() is called. Fix this by only holding the reference in tusb1210_get_online() freeing it at the end of the function. Note this still leaves a theoretical race window, but it avoids the issue when manually rmmod-ing the charger chip driver during development. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: phy: ti: tusb1210: resolver el bloqueo del cargador-det si el cargador psy no está registrado. El marco power_supply no está realmente manipulado para que haya referencias duraderas en el kernel a los dispositivos power_supply. Específicamente, cancelar el registro de un power_supply mientras algún otro código tiene una referencia a él activa una ADVERTENCIA en power_supply_unregister(): WARN_ON(atomic_dec_return(&psy->use_cnt)); Seguido por power_supply aún se elimina y los datos de respaldo se liberan de todos modos, dejando el código de detección del cargador tusb1210 con una referencia colgante, lo que resulta en un bloqueo la próxima vez que se llama a tusb1210_get_online(). • https://git.kernel.org/stable/c/48969a5623ed918713552e2b4f9d391c89b5e838 https://git.kernel.org/stable/c/25b3498485ac281e5851700e33b97f12c9533fd8 https://git.kernel.org/stable/c/73224a5d2180066c7fe05b4656647601ba08d588 https://git.kernel.org/stable/c/9827caa5105fb16d1fae2e75c8d0e4662014b3ca https://git.kernel.org/stable/c/bf6e4ee5c43690e4c5a8a057bbcd4ff986bed052 •

CVSS: 5.5EPSS: 0%CPEs: 9EXPL: 0CVE-2024-35982 – batman-adv: Avoid infinite loop trying to resize local TT
https://notcve.org/view.php?id=CVE-2024-35982
In the Linux kernel, the following vulnerability has been resolved: batman-adv: Avoid infinite loop trying to resize local TT If the MTU of one of an attached interface becomes too small to transmit the local translation table then it must be resized to fit inside all fragments (when enabled) or a single packet. But if the MTU becomes too low to transmit even the header + the VLAN specific part then the resizing of the local TT will never succeed. This can for example happen when the usable space is 110 bytes and 11 VLANs are on top of batman-adv. In this case, at least 116 byte would be needed. There will just be an endless spam of batman_adv: batadv0: Forced to purge local tt entries to fit new maximum fragment MTU (110) in the log but the function will never finish. Problem here is that the timeout will be halved all the time and will then stagnate at 0 and therefore never be able to reduce the table even more. There are other scenarios possible with a similar result. The number of BATADV_TT_CLIENT_NOPURGE entries in the local TT can for example be too high to fit inside a packet. • https://git.kernel.org/stable/c/a19d3d85e1b854e4a483a55d740a42458085560d https://git.kernel.org/stable/c/5eaeaa72113865661568002bb57d611492451d3e https://git.kernel.org/stable/c/04720ea2e6c64459a90ca28570ea78335eccd924 https://git.kernel.org/stable/c/b3ddf6904073990492454b1dd1c10a24be8c74c6 https://git.kernel.org/stable/c/70a8be9dc2fb65d67f8c1e0c88c587e08e2e575d https://git.kernel.org/stable/c/87b6af1a7683e021710c08fc0551fc078346032f https://git.kernel.org/stable/c/3fe79b2c83461edbbf86ed8a6f3924820ff89259 https://git.kernel.org/stable/c/4ca2a5fb54ea2cc43edea614207fcede5 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
