Vulnerabilities

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> kprobes: Fix check for probe enabled in kill_kprobe()<br /> <br /> In kill_kprobe(), the check whether disarm_kprobe_ftrace() needs to be<br /> called always fails. This is because before that we set the<br /> KPROBE_FLAG_GONE flag for kprobe so that "!kprobe_disabled(p)" is always<br /> false.<br /> <br /> The disarm_kprobe_ftrace() call introduced by commit:<br /> <br /> 0cb2f1372baa ("kprobes: Fix NULL pointer dereference at kprobe_ftrace_handler")<br /> <br /> to fix the NULL pointer reference problem. When the probe is enabled, if<br /> we do not disarm it, this problem still exists.<br /> <br /> Fix it by putting the probe enabled check before setting the<br /> KPROBE_FLAG_GONE flag.

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mmc: rtsx_pci: fix return value check of mmc_add_host()<br /> <br /> mmc_add_host() may return error, if we ignore its return value, the memory<br /> that allocated in mmc_alloc_host() will be leaked and it will lead a kernel<br /> crash because of deleting not added device in the remove path.<br /> <br /> So fix this by checking the return value and calling mmc_free_host() in the<br /> error path, beside, runtime PM also needs be disabled.

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mmc: moxart: fix return value check of mmc_add_host()<br /> <br /> mmc_add_host() may return error, if we ignore its return value, the memory<br /> that allocated in mmc_alloc_host() will be leaked and it will lead a kernel<br /> crash because of deleting not added device in the remove path.<br /> <br /> So fix this by checking the return value and goto error path which will call<br /> mmc_free_host().

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/vkms: Fix memory leak in vkms_init()<br /> <br /> A memory leak was reported after the vkms module install failed.<br /> <br /> unreferenced object 0xffff88810bc28520 (size 16):<br /> comm "modprobe", pid 9662, jiffies 4298009455 (age 42.590s)<br /> hex dump (first 16 bytes):<br /> 01 01 00 64 81 88 ff ff 00 00 dc 0a 81 88 ff ff ...d............<br /> backtrace:<br /> [] kmalloc_trace+0x27/0x60<br /> [] 0xffffffffc45200a9<br /> [] do_one_initcall+0xd0/0x4f0<br /> [] do_init_module+0x1a4/0x680<br /> [] load_module+0x6249/0x7110<br /> [] __do_sys_finit_module+0x140/0x200<br /> [] do_syscall_64+0x35/0x80<br /> [] entry_SYSCALL_64_after_hwframe+0x46/0xb0<br /> <br /> The reason is that the vkms_init() returns without checking the return<br /> value of vkms_create(), and if the vkms_create() failed, the config<br /> allocated at the beginning of vkms_init() is leaked.<br /> <br /> vkms_init()<br /> config = kmalloc(...) # config allocated<br /> ...<br /> return vkms_create() # vkms_create failed and config is leaked<br /> <br /> Fix this problem by checking return value of vkms_create() and free the<br /> config if error happened.

feiskyer mcp-kubernetes-server through 0.1.11 does not consider chained commands in the implementation of --disable-write and --disable-delete, e.g., it allows a "kubectl version; kubectl delete pod" command because the first word (i.e., "version") is not a write or delete operation.

feiskyer mcp-kubernetes-server through 0.1.11 allows OS command injection, even in read-only mode, via /mcp/kubectl because shell=True is used. NOTE: this is unrelated to mcp-server-kubernetes and CVE-2025-53355.

A flaw has been found in Campcodes Online Job Finder System 1.0. This affects an unknown function of the file /index.php?q=result&amp;searchfor=bycompany. This manipulation of the argument Search causes sql injection. The attack can be initiated remotely. The exploit has been published and may be used.
