https://notcve.org/view.php?id=CVE-2024-26634
In the Linux kernel, the following vulnerability has been resolved: net: fix removing a namespace with conflicting altnames Mark reports a BUG() when a net namespace is removed. kernel BUG at net/core/dev.c:11520! Physical interfaces moved outside of init_net get "refunded" to init_net when that namespace disappears. The main interface name may get overwritten in the process if it would have conflicted. We need to also discard all conflicting altnames. Recent fixes addressed ensuring that altnames get moved with the main interface, which surfaced this problem. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: net: corrige la eliminación de un espacio de nombres con nombres alternativos en conflicto. • https://git.kernel.org/stable/c/673edcffa0960fc154085d639e10f80b6317d3bd https://git.kernel.org/stable/c/7663d522099ecc464512164e660bc771b2ff7b64 https://git.kernel.org/stable/c/f7a69786fe5ec75d1cdd71b465e74a1adc68ef40 https://git.kernel.org/stable/c/a2232f29bf52c24f827865b3c90829c44b6c695b https://git.kernel.org/stable/c/e855dded4b70d1975ee7b9fed0c700391e3c8ea6 https://git.kernel.org/stable/c/8072699aa9e67d1727692cfb3c347263bb627fb9 https://git.kernel.org/stable/c/d09486a04f5da0a812c26217213b89a3b1acf836 •

https://notcve.org/view.php?id=CVE-2023-52616
In the Linux kernel, the following vulnerability has been resolved: crypto: lib/mpi - Fix unexpected pointer access in mpi_ec_init When the mpi_ec_ctx structure is initialized, some fields are not cleared, causing a crash when referencing the field when the structure was released. Initially, this issue was ignored because memory for mpi_ec_ctx is allocated with the __GFP_ZERO flag. For example, this error will be triggered when calculating the Za value for SM2 separately. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: crypto: lib/mpi: corrige el acceso inesperado al puntero en mpi_ec_init Cuando se inicializa la estructura mpi_ec_ctx, algunos campos no se borran, lo que provoca un bloqueo al hacer referencia al campo cuando se lanzó la estructura. Inicialmente, este problema se ignoró porque la memoria para mpi_ec_ctx se asigna con el indicador __GFP_ZERO. Por ejemplo, este error se activará al calcular el valor Za para SM2 por separado. • https://git.kernel.org/stable/c/d58bb7e55a8a65894cc02f27c3e2bf9403e7c40f https://git.kernel.org/stable/c/0c3687822259a7628c85cd21a3445cbe3c367165 https://git.kernel.org/stable/c/2bb86817b33c9d704e127f92b838035a72c315b6 https://git.kernel.org/stable/c/bb44477d4506e52785693a39f03cdc6a2c5e8598 https://git.kernel.org/stable/c/7ebf812b7019fd2d4d5a7ca45ef4bf3a6f4bda0a https://git.kernel.org/stable/c/7abdfd45a650c714d5ebab564bb1b988f14d9b49 https://git.kernel.org/stable/c/ba3c5574203034781ac4231acf117da917efcd2a https://lists.debian.org/debian-lts-announce/2024/06/ •

https://notcve.org/view.php?id=CVE-2023-52615
In the Linux kernel, the following vulnerability has been resolved: hwrng: core - Fix page fault dead lock on mmap-ed hwrng There is a dead-lock in the hwrng device read path. This triggers when the user reads from /dev/hwrng into memory also mmap-ed from /dev/hwrng. The resulting page fault triggers a recursive read which then dead-locks. Fix this by using a stack buffer when calling copy_to_user. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: hwrng: core: soluciona el bloqueo de falla de página en mmap-ed hwrng Hay un bloqueo en la ruta de lectura del dispositivo hwrng. Esto se activa cuando el usuario lee desde /dev/hwrng en la memoria y también realiza mmap-ed desde /dev/hwrng. • https://git.kernel.org/stable/c/9996508b3353063f2d6c48c1a28a84543d72d70b https://git.kernel.org/stable/c/eafd83b92f6c044007a3591cbd476bcf90455990 https://git.kernel.org/stable/c/5030d4c798863ccb266563201b341a099e8cdd48 https://git.kernel.org/stable/c/c6a8111aacbfe7a8a70f46cc0de8eed00561693c https://git.kernel.org/stable/c/26cc6d7006f922df6cc4389248032d955750b2a0 https://git.kernel.org/stable/c/aa8aa16ed9adf1df05bb339d588cf485a011839e https://git.kernel.org/stable/c/ecabe8cd456d3bf81e92c53b074732f3140f170d https://git.kernel.org/stable/c/6822a14271786150e178869f1495cc03e • CWE-400: Uncontrolled Resource Consumption •
